- You can use rectangle() to draw on the display.
- You can use the Computer Vision function insertShape() to write into an array (probably displaying the array later)
- You can use assignment statements to write into an array (probably displaying the array later)
Highlighting a portion of an image created from a matrix using "pcolor"

I have created an image to visualize a matrix I have using pcolor function. The plot is shown below. I want to highlight elements of the matrix located in the range [65 95] using a square frame or anything else. I have created a square around this area manually but it is not perfect. Any idea?
Thanks

xloc = 65:95;
yloc = 65:100;
YourArray(yloc, xloc([1 end]), :) = 255; %left and right edges
YourArray(yloc([1 end]), xloc, :) = 255; %top and bottom edges
