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
