How to save two variables in a mat file?
Check the content of the file using the whos function. Create two variables and save them in a version 7.3 MAT file called example.mat. You can also use command syntax for the save operation. Create two variables and save them, without compression, to a version 7 or 7.3 MAT file called myFile.mat.

How does MATLAB save data to mat files?
By default, MATLAB compresses the data it saves to MAT files. MATLAB also uses Unicode character encoding when saving character data. Specify the -v6 option if you want to disable both features for a particular save operation.
How to save a mat file with data compression disabled?
To write a MAT file that you will be able to read with one of these versions, save it to the file with data compression disabled. The information returned by the whos -file command is independent of whether the variables in that file are compressed or not.
How does MATLAB store data in contiguous memory?
Also note that while MATLAB stores numeric arrays in contiguous memory, this is not the case for structures and cell arrays. When reading data from a binary file with fread, it is a common mistake to specify only the data class in the file and not the data class that MATLAB uses once it is in the workspace.
How to keep changes to a variable made inside a function?
What it means is that a new variable with a new scope is created with the same value of x. So any change that happens to the new x is not reflected in the x outside the scope of the function. If you want to retrieve the value from the function, you can use the return statement (as you have used). return returns the value of the function.
What is the difference between save and save(filename, variables)?
save(filename, variables) saves only the variables or fields of a structure array specified by variables. save(filename,variables,fmt) saves to the file format specified by fmt. The variables argument is optional. If you don’t specify variables, the save function saves all variables to the workspace.
How to save two variables in an ASCII file?
Create two variables, save them to an ASCII file, and then view the contents of the file. p = rand(1.10); q = units (10); save (‘pqfile.txt’, ‘p’, ‘q’, ‘-ascii’) type (‘pqfile.txt’) The type function displays the content of the file. Alternatively, use command syntax for the save operation.
