Not enough input arguments.

Hi,

I'm trying to use the repmat function :

for i=1:size(test,1)
    a=(test{i,2 :4} - train{: , 2:4})
    b=repmat(a)
end

But I only obtain this error :

Error using repmat
Not enough input arguments.

You should believe what the error message is telling you.

Yes, what repmat suppose to do here, repmat(A,n) returns an array containing n copies of A in the row and column dimensions. May be you missed the "n" to be define, as an example

>> a=1:3
a =
     1     2     3
>> repmat(a)
Error using repmat
Not enough input arguments.

You should believe what the error message is telling you. In the documentation for repmat, you will find no single-argument syntax like the one you've used.
