I have an data in matrix 100X6 (the first two columns are x1 & y1, other two columns x2 & y2 etc.) and I would like to make a plus and minus 10% in each y column data!! old matrix: x1 y1 x2 y2 x3 y3 " " " " " " " " " " " " " " " " " " new matrix: x1 y1 y12 y13 x2 y2 y22 y23 x3 y3 y32 y33 " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " then plot x1 with y1,y12, and y13 data then plot x2 with y2,y22, and y23 data etc

you do not need to create new columns to do this, just add/subtract the 10% in the plot command directly
plot(x1,y1,'k-',x1,0.9*y1,'r:',x1,1.1*y1,'r:')
