How is the save function used in Matlab?
The save function in MATLAB is used to save variables to a file. Its basic usage is as follows:
Save all variables in the current workspace to a file named “filename”.
Save the specified variables to a file named filename. In this case, variables can be a character vector, string array, or cell array containing variable names.
Save the specified variables in the specified format to a file named filename. The format is a character vector or string used to specify the format for saving. Common formats include:
- ‘-ascii’: Save data in ASCII format (default format).
- Save the data in MATLAB format.
- Save data in MATLAB format with specified version (X) by using ‘-vX’.
For example:
save(‘data.mat’) saves all variables in the current workspace to a file named data.mat.
save(‘data.mat’, ‘x’, ‘y’, ‘z’) saves variables x, y, and z to a file named data.mat.
save(‘data.txt’, ‘x’, ‘y’, ‘z’, ‘-ascii’) saves variables x, y, and z in ASCII format to a file named data.txt.
You can also control how the data is saved by specifying the format, compression, etc. Additional usage and options can be found in MATLAB’s official documentation.
