Random matrix with boundaries
I would like to generate a 15 * 20 random matrix ranging from -2 and 2, and then find the maximum and minimum values inside the matrix. Then using loops, set all matrix elements that exceed the value of 1.2 to the maximum while setting the elements below -1.2 to the minimum. Can someone help me please? ... 12 Apr 2010 08:05

To find X at which Y is maximum
Hii, I have X, Y data. I need to find maximum of Y between equal intervals, i.e., i=255000:5000:570000; peak=max(Y(i),Y(i+5000)); Now I need to find X at which Y is maximum since I need a plot between Max of Y and X at which it is occurring. Can someone help me?? Thanx ... 13 Apr 2010 06:10
