hi, im trying to comment out this text:

 Write a MATLAB script that will load a *.csv (comma separated value) file containing
two column vectors; the first vector containing time values, the second amplitude
values. The script should compute the discrete fast Fourier transform of the amplitude
values and plot the Single-Sided Power Spectrum. MATLAB help can be found
at:

but %{

%} does not work. this happens sometimes. would you know why?

Are there special rules for block commenting?
