Matlab help
Thursday, June 28th, 2007I figure I’ll try this resource, too.
what I have: a data file with three columns: frequency, temperature, and “eta”. I want to make a 2D plot of eta vs frequency and temperature, like this:
What I have done is to write a code that reads the file and stores the third colum, the eta values, in a 2-D array – so for example, data[12,8]=0.8713. However, I now need to re-scale the axes so that they read from 0.1 to 1 or from 1 to 8 instead of just using the x/y indices (1 to 80, etc). Do people know how to do that? or, maybe instead I should do a scatterplot of z at location [x,y] instead of the surfc command that produced the above image?
thanks.
