This error is indicating that the first input, X, into "trapz" is not the proper size.
The X input must be a uniform scalar spacing, or a vector of coordinates.
- If X is a scalar, then it specifies a uniform spacing between the data points and trapz(X,Y) is equivalent to X*trapz(Y).
- If X is a vector, then it specifies x-coordinates for the data points and length(X) must be the same as the size of the integration dimension in Y.
For more information on these inputs, see the following documentation page:
You can check your variables to ensure they are as expected by using the debugger. The following link explains how you can use the debugger to find the issue:
