Hi everyone! I am having trouble with the following: I have built a 31 row by 3 columns ceros matrix and I am trying to index values to each column, I want my first column to go from 140 to 440(this are lengths), but when trying to do so my values start from 0, then 140, then 440... Then in the second column I want the values of column 1 to appear because I need to compare how many lengths are being acumulated( this to later build a histogram..) I would very much appreciate your help!

Your code has only one error when you set the C matrix in 300 rows and 3 columns, and try to fill it with numbers starts in 140 to 440 with steps of 1 unit you have a 301 elements so, the C matrix needs to be 301 rows not 300. (if the number starts in 141 so, there is a 300 elements vector)
the code:
C=zeros(301,3);
C(:,1)=[140:1:440]'
