If you don't have the Computer Vision System Toolbox and want to compute the scale space, why don't you just do the smoothing yourself.
For each sigma corresponding to a different scale, you can convolve the image with a gaussian filter using the imfilter function.
im_sigma = imfilter(im,fspecial('gaussian',hsize,sigma));
