Dear all,
I have the file as attached. the format is dicom (.dcm)
How to multiply all the pixel number of each slice with their own rescale slope(in dicominfo) in each slice?
**that means each slice have their own rescale slope value.
so that the new pixel value will come out when I view this images.

What leads you to believe the rescale slope and intercept might be different for each slice?

In general you should remember to include the intercept as well, although apparently that is 0 for this dataset.
unzip jaszakspect.zip
IM = dicomread('jaszakspect.dcm');
size(IM)
info = dicominfo('jaszakspect.dcm');
[min(IM(:)) max(IM(:))]
IM = double(IM)*info.RescaleSlope + info.RescaleIntercept;
[min(IM(:)) max(IM(:))]
