Problem-saving the results from the loop

1 view (last 30 days)
Hello. I need help
I have this code, I want to save the results from Sbar1.
Nn=4;
for i=1:1:Nn
for X1=0:45:360
c= cos(X1*pi/180)
s= sin(X1*pi/180)
R= [1 0 0; 0 1 0; 0 0 2]
A1= [c^2 s^2 2*s*c; s^2 c^2 -2*s*c; -s*c s*c c^2-s^2]
Sbar1= [R*A1^-1*R^-1*S*A1]
end
end

Thanks Madhan Ravi for the idea,
You could apppend the values of Sbar1 at each iteration to another variable, say result like this
Nn=4;
result = double.empty(0,3);
for i=1:1:Nn
for X1=0:45:360
c= cos(X1*pi/180);
s= sin(X1*pi/180);
R= [1 0 0; 0 1 0; 0 0 2];
A1= [c^2 s^2 2*s*c; s^2 c^2 -2*s*c; -s*c s*c c^2-s^2];
Sbar1= [R*A1^-1*R^-1*s*A1];
result = [result,Sbar1]
end
end
Here first 3 columns of result will be the Sbar1 of first iteration, next 3 columns will be Sbar1 of second iteration, and so on.

I'm assuming by save, you mean to write the data into an external file. Have a look at save() (documentation here).
With this, you can save workspace variables into a file and you can set various options like the file type, the variables, the format, etc.

No , the OP wants to save the results of each iteration into the variable.

Ohh thinking now, I think that seems more sensible.
