mtrain1 = size(Xtrain1,1);

nw = size(Xtrain1,2);

when i run the above code , i face the following error:

Not enough input arguments.

Error in movie_kernel (line 28)

mtrain1 = size(Xtrain1,1);

What is this error, and how to solve this error, thanks

huh? why is size executing movie_kernel? I don't see that happening in those lines of code unless Xtrain1 executes a script or something like that

You have a function named movie_kernel that expects to be passed one or more parameters, including a parameter it refers to as Xtrain1. However when you invoked the function you did so without providing enough input parameters.

A common cause for these kinds of problems is trying to execute a function by pressing the green Run button. When you press the Run button, the current script or function is executed without any input parameters.
