Hello! This SHOULD be a simple fix, and I've spent some time reading answers to similar question.... but still can't manage to find a fix. I'm trying to use fplot to plot lift as a function of length L.
q_l = ka.*sqrt(L.^2 - x.^2)
I get the following warnings (no curve is plotted):
Warning: Function behaves unexpectedly on array inputs. To improve performance, properly vectorize your function to return an output with the same size and shape as the input arguments.
Warning: Error updating FunctionLine.
The following error was reported evaluating the function in FunctionLine update: Unable to convert expression into double array.
