not enough input arguments

Im new to MATLAB and im having trouble creating a simple function.

When I call the function:

a = [268.32,0, 120,0,240];
[T] = transformation_matrix(a);

I keep getting "not enough input arguments" and error on line 3.

How can i fix this?

function [T] = transformation_matrix(l,x1,x2,y1,y2) 
 
costheta = (x2-x1)/l;
sintheta = (y2-y1)/l;
 
t = [costheta sintheta 0 0 0 0;
    -sintheta costheta 0 0 0 0;
    0 0 1 0 0 0; 
    0 0 0 costheta sintheta 0;
    0 0 0 -sintheta costheta 0;
    0 0 0 0 0 1];
 
end

You have written the function to accept 5 inputs: l,x1,x2,y1,y2

However, when you call it, you are only using one: a, which gets assigned to l.

I think what you want to do instead is

T = transformation_matrix(268.32,0, 120,0,240);

yes this is what i ended up doing! thank you!

a = [268.32,0, 120,0,240];
a = num2cell(a)
T = transformation_matrix(a{:});
