Loading X, Y, and strain data from multiple files in Tecplot 360

Dear All

I am using tecplot to visualize my data. Now I came across a problem as I have three files (created using Matlab). Each file is having a big matrix having data. One file is having X coordiates, second one is having Y coordinates and third one is having the strain data of these two coordinates. I like to import and plot contour using this data. It will be nice if some one can guide me in this matter.

Regards
