How to Read .nc File in Matlab

Definition of Matlab Read CSV

Matlab provides different options to users; the read CSV is one of the options in Matlab. Suppose we need to store plain text and you are familiar with the comma separated format. At that time we tin can use CSV file format. Basically, CSV file format is homo-readable well equally it is uniform with dissimilar types of software applications such as Matlab. Considering of this reason, the CSV file format is widely used and Matlab provides the unlike types of predefined functions for reading the records from the CSV file. In that location are several options bachelor in Matlab for reading CSV files equally per our requirement we can employ respective options.

Syntax:

Grand = csvread (specified csv file proper name)
1000 = csvread (specified csv file proper name, row offset 1, column offset 1)
M = csvread (specified csv file name, row offset 1, column commencement 1,[ row offset 1 cavalcade outset ane row offset two column offset 2])

Explanation

Basically, there is multiple syntaxes to read CSV files in Matlab as shown. In the get-go syntax, nosotros utilise a simple syntax to read CSV files, here M is used for an assortment that must contain integer values, and specified CSV file proper name means actual file proper noun that nosotros need to read in Matlab.

In the 2nd syntax additionally provides the offset value to the array. That means first-row kickoff and first column offset for example nosotros tin can specify the starting value like 0, 0 in the file.

In the third syntax, we provide the range of offset value that means the bounded value that means row offset one and row start 2 too as nosotros also provide column offset ane and column offset two. For example, nosotros tin can specify the range instead of row values.

How to read CSV in Matlab?

Now let's run across how we can read the CSV file in Matlab as follows. Basically, we can apply iii different functions to read CSV files in Matlab as follows.

1. Read CSV file by using readtable() function:

This is the first manner to read a CSV file in Matlab. In which that readtable() function reads all records from the file and saves them into the tabular array and that tabular array has a column name. if the CSV file does non have any heading for the column at that time readtable() function is assigned by default variable name for column and it starts from var1.
For example: info = readtable(specified CSV file proper name with extension)

Caption:

In the higher up example, we utilize the array proper noun for that info and after that, we use readtable() function with a specified CSV file name as shown in the above example.

two. Read CSV file by using readmatrix() function:

This is some other manner to read a CSV file in Matlab, in which we tin can read records from the CSV file into a matrix form.
For example: info = readmatrix(specified CSV file name with extension)

3. Read CSV file past using readcell() function:

By using this function we read records from a CSV file into a cell format.

For example: info = readcell(specified CSV file name with extension)

Examples

Now let'south run across the different examples of reading a CSV file in Matlab as follows. Offset, we need to create a new CSV file, hither we created a program2.csv file and we added some value every bit shown in the beneath screenshot as follows.

Now create a new script and below code as follows.

A = readtable('program2.csv')
disp(A)

Explanation

In the above example, we employ readtable() role to read records from the program2.csv file, after that, nosotros display that array past using disp () function equally shown in the in a higher place case. The final output of this program nosotros illustrated by using the post-obit screenshot as follows.

Encounter in in a higher place screenshot information technology takes past default column name var1, var2, and var3. If we need to print the specific range then nosotros can use the following lawmaking as follows.

A = readtable('program2.csv','range','A1:B1')
disp(A)

Explanation

In the above programme, we utilise the readtable() part with a specific range option as shown. In this example, we provide a specified range that is A1:B1. The final output of this program we illustrated by using the following screenshot as follows.

Sometimes we need to impress the specified portion of records at that time we can apply the readtable() part with different options. Matlab provides the ReadVariableNames(), by using this choice we tin can specify the commencement row from the csv file. When we use this option then we tin can easily determine which variable is imported or not.
At present allow's meet another instance of the readmatrix() function as follows.

Here we use an already created CSV file that we used in the in a higher place example.

A = readmatrix('program2.csv')
disp(A)

Explanation

In the in a higher place case, nosotros use the readmatrix () office and here we laissez passer a CSV file that is a program2.csv file. Here we can also use the detectImportOptions() function and it is used to discover and import the specified option that nosotros require. With this function, we tin can as well employ the range pick as per our requirement. The last output of this program we illustrated past using the following screenshot equally follows.

Now permit'due south see the 3rd option to read the CSV file in Matlab equally follows.

Matlab provides the third function to read the CSV file that is readcell() function. By using this function we tin read the records from the CSV file and salvage into a cell format. Allow'south see an example as follows.

A = readcell('program2.csv')
disp(A)

Explanation

In the above example, nosotros utilize readcell() function, by using this function we tin can read records from a CSV file and shop them into the prison cell. The final output of this program nosotros illustrated by using the following screenshot as follows.

Every bit per our requirement, we can provide the range inside the role to fetch the specified records.

Conclusion

We hope from this article you learn Matlab read CSV. From the to a higher place commodity, we have learned the basic syntax of read CSV and we besides see different examples of read CSV. From this article, we learned how and when we use Matlab read CSV.
