Save all values of a calculation through a loop in a file

V=[31:1:61];

angle=2;

for V=(31:1:61)

save myresults UVW0 -mat

end

Hello,

I need your help please!

I want to save all the results for UVW0 in a file bu my current program only saves the last results of the calculation in the mat file.

How can I save all the results for each calculation in the mat file?

Many thanks in advance!

"How can I save all the results for each calculation in the mat file?"

The standard, efficient, simple approach is to store the data in one array and save it once after the loop.

But why do you need a loop anyway? That calculation is easy to perform without a loop:

V = 31:1:61; % got rid of the superfluous square brackets too
angle = 2;
UVW0 = V .* [cos(angle);0;sin(angle)]

UVW0 = 3×31

Thanks a lot!

I used the loop to calculate V*cos(angle) for each element of V from 31 to 61.
