To create a correlation matrix in Igor Pro

• Fit your data, with the "Create Covariance Matrix" check box checked under "Output Options"
• Copy the following two commands
  • Duplicate M_Covar, CorMat
  • CorMat = M_Covar[p][q]/sqrt(M_Covar[p][p]*M_Covar[q][q])
• Go the command window. Below the red line, paste these two lines into the single command line and press (you can also execute these commands one at a time).
• Finally, under the "Windows" menu, select "New Table" and then choose CorMat from the list of options. This will create a new table, containing the correlation matrix

To find this from within Igor Pro, under the Help Menu, select Igor Manual, and then in the search pane, search for "correlation matrix."
