matlab is basically telling you that it can't find the function:
which mvnrnd
will probably result in: 'mvnrnd' not found
mvnrnd is part of the statistics toolbox, type 'ver' in matlab and see if you have it.

I don't have Statistics Toolbox in my Matlab, how can I get it?

function p = mygmm(x1,x2, w1, mu1, sigma1, w2, mu2, sigma2)
assert(w1 +w2 == 1.0, 'The weights of the components must add to 1.0')
assert(all([w1 w2] >= 0 & [w1 w2] <=1)),
p = w1 * mvnpdf([x1 x2], mu1, sigma1) + w2 * mvnpdf([x1 x2] , mu2, sigma2);
end
By running the above code I get the following error message:
Not enough input arguments.
