Have matlabFunction create a function handle with two inputs even when the symbolic expression uses only one.

So I have symbolic expressions which sometimes use only one of the two inputs set in their definition. I want matlabFucntion to create a function handle with the same number of input variables as the symbolic expression, and to place their inputs in the same order as they were defined symbolically.

Here is an example code of what I have done, which I know misses to accomodate the dX_mf function handle's inputs correctly.

syms dX(X,Y) dY(X,Y)
dX = Y
dY = X+Y

dX_mF = matlabFunction(dX) % Here I would want to have dX_mF = @(X,Y) instead of dX_mF = @(Y)
dY_mF = matlabFunction(dY) % This works great, with dY_mF = @(X,Y)

Have a nice day,

Use

dX_mF = matlabFunction(dX, 'Vars' [X Y])

The second part which allows you to change the order of the variables of the function handle inputs.

There is more information in the documentation of matlabFunction.
