YUV video processing in Matlab

I am using this function I got from the File Exchange:

    >>[Y,U,V]=yuv_import('test.yuv',[176 144],150,0)

I got this from: Convert YUV CIF 4:2:0 video file to image files It prints out the Y, U and V components of the yuv file test.yuv. When I typed:

    >>Y

It displayed:

    Y = 

      Columns 1 through 5

And..

    >>size(Y)

displayed:

    ans =

         1   150

Doing the same for U and V components also showed the same results.

And also..

    >>Y(150)

displayed:

    ans = 

        [144x176 double]

What I want is make an array for Y, U and V that has the dimensions [numberOfFrames height width] or [150 144 176]. How can I do this?

yuv = cat(3, Y, U, V);
