What is wrong with this function call? It's so basic but don't know what I am missing.
The error is "Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters."
load('mnist.mat', 'testX');
% save('testX'); commented it based on the reply I got for this question
x=testX; % testX is a 529*784 matrix
k=5; numIter=6;
[mu, cll, ill] = gmm(x, k,numIter)
% the function definition starts like this in another file
% function [mu,CLL,ILL] = gmm(x,K,numIter)

Oh, it's working now!!!!
Turns out this posted code excerpt was perfectly okay. Inside the function definition, there was one ) missing for one line.
Thanks for the save() suggestion.

I do not see any problem with the code extract that you posted.
Perhaps the error is inside gmm function .

%if true
x = load('mnist.mat', 'testX');
k=5;
numIter=6;
function [mu, cll, ill] = gmm(x, k,numIter)
Assign x directly when loading

Thanks again for the reply. What I meant in my previous answer was I did in the way you proposed in the beginning. I didn't know that VBBV's answer and your answer would give different result into x and that's why i commented like that thinking they give same x.
I didn't see any button for accepting your answer..

Assigning the output of load() is a good idea... it just isn't the reason you had the problem in this situation, and the change was not coded for correctly in VBBV's answer.
