Saving a matrix from a function file
显示 更早的评论
Hi, I have created a function file and I need one of the values from the middle of that function file to plot it against time.
That function file is in a continuous loop, but when I save that one particular matrix it saves only the first value and plots a straight line against time. I cant figure out how I can create a plot with the varying value for that variable
This is the command that I am using to save that matrix. 'x', 'y' and 'z' are all variables. 'x' changes with time.
F = x*y + z;
save('F.mat','F');
Do i use a while loop or something else?

Could you share more of your code to see what exactly is happening, maybe as an attachment (see paper clip)?
Note, that in the above code F is a scalar, not a matrix. To make it a matrix (or vector) use (e.g.)
for ii = 1:n
...
F(ii) = x(ii)*y + z;
...
end
assuming that x is a vector and y a scalar.

Use dot notation to operate with arrays:
x = rand(10,1);
y = rand(10,1);
z = rand(10,1);
F = x.*y + z; % MIND THE DOT
save('F.mat','F');
F =
0.5858
0.6918
0.8671
0.1993
0.1371
0.9017
1.2694

Just attach (paper clip icon) your code as a whole to your question.
