You can use the Eval () function, for example:

b = ones (+);
For i = 1:10
<span style= "White-space:pre" >	</span>eval ([' Var ', num2str (i), ' = ', ' B (i,:) ', '; ']);
End


Results are 10 variables var1, var2 ... Var10 are assigned to each row of the B matrix, respectively.




You can also use the call function in the eval () function, for example:

For i = 1:3
eval ([' X ', Num2str (i), ' = ', ' Sum ([2, 3]) ', '; ']);
End



The eval () function is also used inside other functions, such as:

For i = 1:5 figure
;
Imshow ([' Image ', num2str (i)])% loop generates the variable name and displays the corresponding matrix end with Imshow ()
