Illustration of Writing variables to a file:

For illustration, in the below session in the Command Window, 3 variables are generated; these are then exhibited using who. Then, the variables are saved to file named 'sess1.mat'. The who function is then used to show the variables stored in that file.

>> mymat = rand(3,5)

mymat =

   0.9501   0.4860   0.4565   0.4447   0.9218

   0.2311   0.8913   0.0185   0.6154   0.7382

   0.6068   0.7621   0.8214   0.7919   0.1763

>> x = 1:6;

>> y = x.^2;

>> who

Your variables are:

mymat x y

>> save sess1

>> who -file sess1

Your variables are:

mymat x y

To save only one variable to a file, the format is as shown below:

save filename variablename

For illustration, only the matrix variable mymat is saved in a file known as sess2

>> save sess2 mymat

>> who -file sess2

Your variables are:

mymat
