I would like to pick 53 (or any other arbituary number) data points from my data set by selecting the index of the matrix.
I would like to know the y values of 53 evenly spaced values of x. I want to plot the same graph but with only 53 data points. Ive attempted this by creating a linspace of length 53 with max and min values corresponding to the data, then trying to use the 'find' function for when my x array is equal to these numbers to find the array indices, and then finally finding the corresponding y-values.
dx = linspace(minx,maxx,53);
inx = find(x == dx);
dy = y(inx);
what I find very confusing is that the inx indexes are much larger than the size of the x and y arrays ( a factor of about 80 for some reason) so I cant find the corresponding y values as it exceeds the array.
Any help would be much apprieciated, cheers
