%Describing the Denavit-Hartenberg parameters
T =[cosd(theta) -(sind(theta)) 0 a;
sind(theta)*cosd(alpha) cosd(theta)*cosd(alpha) -sind(alpha) -d*sind(alpha);

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.

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
