how to create num2str in a variable

Hello,

How can I write the left hand side's expresion using num2str instead of f2 to avoid changing them every time when I change the f2 to another value?

your help is apreciated.

f2=50;
X1_f2_Y1 = Z1p;
X2_f2_Y2 = Z2p;
X3_f2_Y3 = Z3p;
X4_f2_Y4 = Z4p;

and also how it works if these expresions are used in save command?

save('E:\myfiles\data.mat','X1_f2_Y1 = Z1p');

Can you do this? Yes.

Should you do this? Generally we recommend against it.

str = ['X',num2str(1),'_f',num2str(2),'_Y',num2str(1),' = Z1',num2str(1),'p']
