how to multiply 3d matrix with 2d matrix

i have one matrix 'H' with dimension of 2976 X 2976 and another one is 'Y' of 2 X 2 X 2976. i want H'*y and for this i use " Y(p,q,:)= H'*squeeze(y(p,q,:))". But due to use of squeeze function i'm getting correct values at first running of code but after first running code if i again run code i got different values at second attempt i.e values vary at every time if i run code.I'm attaching snapshot of my result with this. anyone can solve this issue, it will be very helpful.

the best solution is.. take a of size 3,3... and b of size 2,2,1...multiply it.. check manual calculation also.. cross check it.. you can easily find how matlab works.. then you can apply for big sized matrix
