Matrix Dimensions must agree

With the following function, on the line fitted_Curve, there is the error that matrix dimensions must agree.

function f = functionToMinimise(x,Input,Actual_Output)
% f = x^2 %f and x are dummy variables
global c_x beta
Fitted_Curve = (1/(sqrt(x)*sqrt(beta)))*(c_x-asinh(sinh(c_x)*exp(x*Input*2*pi)))

What is wrong, and what to look for with this error message? Input is the vector, everything else is a coefficient.

I had to assume some things about calling your function, since you did not provide enough information to actually try to run your code. The following function (that calls your function) worked just fine:

function answerTest()

global c_x beta

c_x = 1;
beta = 1;

functionToMinimise(1,rand(1,3),1)

end

function f = functionToMinimise(x,Input,Actual_Output)
% f = x^2 %f and x are dummy variables
global c_x beta
Fitted_Curve = (1/(sqrt(x)*sqrt(beta)))*(c_x-asinh(sinh(c_x)*exp(x*Input*2*pi)));
f = Fitted_Curve;

end
