what does "read pixels" mean exactly? What is the input and what is the wanted output?

What exactly are you expecting a histogram of only white pixels to show?!

It still doesn't make sense what you want. Focus on the result you want. The fact you think you should use a for loop is irrelevant to what you are actually trying to get as an end result.

Judging from your last comment what you want is a plot of the number of black pixels in each column of the image:
figure; area( sum( ~bw ) )
should give you this.
