Hi,
How can I get input of function when the output is constant?
In this function, output = f(input)
output is constant and input should be controlled to match the output.
Thank you.

When it is a vector, do you want to return a scalar output or do you want to return one copy of the constant for each input?
F = @(x) constant * ones(size(x))
