I have a 132X132 correlation matrix, and I want to label the values that show high correlation (these values happen to be different brain areas). What are the ways I can go about it?

The 132X132 matrix is stored as a variable invfish, and these 132 points are infact brain areas, the names of which are stored in a different variable {names} , a cell of dimension 132X1.

I wish to generate a plot such that areas of high correlation are clustered together, and I need to label those areas by accesing their ID from the cell, {names}
