Not enough input arguments

Im running this code in matlab and i get not enough input arguments for the second line

[m n] = size(coef)

anyone know why this is and how it can be solved?

code

function Y = spatFilt(x, coef, dimm)

    [m n] = size(coef)

    %check for valid dimensions
    if(m<dimm)
        disp('Cannot reduce to a higher dimensional space!');
        return
    end

    %instantiate filter matrix
    Ptild = zeros(dimm,n);

    %create the n-dimensional filter by sorting
    i=0;
    for d = 1:dimm

     if(mod(d,2)==0)   
        Ptild(d,:) = coef(m-i,:);
        i=i+1;
     else
        Ptild(d,:) = coef(1+i,:);
     end

    end

    %get length of input signal
    T = length(x);
    %instantiate output matrix
    Y=zeros(dimm,T);

    %filtering
    for d = 1:dimm
       for t = 1:T 
       Y(d,t) = dot(Ptild(d,:),x(:,t));
       end
    end

    return

Please post a complete copy of the error message.

hi when i run the code this message appears

>> spatFilt Error using spatFilt (line 15) Not enough input arguments.

[Jan]

I'd expect that there are some further lines in the message.

Did you create a function called "size" by your own? See:

which('size', '-all')

[zamire ali]

no your right i havnt given size any parameters would you sggest using which('size', '-all') as the parameter

[Jan]

No. You description sounds like this command failes:

[m, n] = size(coef);

Matlab's original size command is satsified with one input. Then you might have created another function called "size", which requires more inputs. Then the output of "which('size', '-all')" would reveal all functions files which are called "size.m".

Or the complete error message might reveal, that coef is a function handle and not an array, such that size(coef) calls the function stored in coef but without any arguments.

Therefore I ask again for posting everything which appears in the command window, when the error occurs.

Please post also how you call the function spatFilt.
