Hi Everybody,

I have next problem. In my program I use rgb2gray function. On two
computers (one have MatLab 7.0.*, another - MatLab 7.3.*) it works
without problem. On the third computer with MatLab 7.0.* an error
comes : "??? Undefined command/function 'rgb2gray' ".

What could it mean? or why does this error come? has anybody some
ideas?

Thank you very much,

Tim(ur)

on that third computer you do not have the image processing toolbox
installed. you can check this with the "ver".
