sudheer - if you are calling this function from the command line (or another piece of code) as simply
trans
then you will get this error. The function signature
function T = trans( a, d,alpha, theta)
is telling you that you need to provide four input paramters: a, d, alpha and theta. And so the function should be called like
trans(1,0.5,45,-74)
The above inputs are for example only...I don't know what the units for the inputs should be.

sudheer - you will need to show the code that you are using and the full error message.

Can you show us exactly how you're calling your function and the full and exact text of the error message you receive (all the text displayed in red, and if there is any all the text displayed in orange) when you try to call it?

I do not observe any error when used in the manor that Geoff suggested.
trans(1,0.5,45,-74)
function T = trans( a, d,alpha, theta)
T =[cosd(theta) -(sind(theta)) 0 a;
sind(theta)*cosd(alpha) cosd(theta)*cosd(alpha) -sind(alpha) -d*sind(alpha);
sind(theta)*sind(alpha) sind(alpha)*cosd(theta) cosd(alpha) d*cosd(alpha);
0 0 0 1 ];
end
