Won't show me my variable?

Hello,

So when I run the code I don't get my variable "I" on the right side. The variable is in the following part od the code:

if Ms >=3.5

I = 21.29 * Ms - 69.4;

elseif Ms >= 2

I = 2.73 * Ms - 4.47;

elseif Ms >= 0

I = 0.5 * Ms;

elseif Ms >= (-2)

I = 0.5 * Ms;

elseif Ms >= (-3.5)

I = 2.73 * Ms + 4.47;

elseif Ms < (-3.5)

I = 21.29 * Ms + 69.4;

end

What could be the problem?

Ms is non-scalar, and contains false values.

The MATLAB approach is to use logical indexing, not IF/ELSEIF/END.

What can I change to fix it?

"What can I change to fix it?"

Use logical indexing, e.g.:

I = 0.5 * Ms;
X = Ms>=3.5;
I(X) = 21.29 * Ms(X) - 69.4;
X = Ms>=2 & Ms<3.5;
I(X) = 2.73 * Ms(X) - 4.47;
X = Ms<(-2) & Ms>=(-3.5)
I(X) = 2.73 * Ms(X) + 4.47;
X = Ms<(-3.5);
I(X) = 21.29 * Ms(X) + 69.4;

It worked.
