Hello!!

I have given a positions.mat file with two columns for x- and y-Coordinates of points in a plane.

In my *.m-file I want to access these coordinates and find the minimum and maximum value in both directions (x and y).

I want to assign the following names to these values: Xmin, Xmax, Ymin, Ymax.

Can somebody help me with the code in my .m file?

THANK YOU!!

Hi!

This code will help in getting the maximum and minimum value of X and Y coordinates:

m = matfile('positions.mat');
pos = m.pos;
Xmin = min(pos(:,1));
Xmax = max(pos(:,1));
Ymin = min(pos(:,2));
Ymax = max(pos(:,2));

Please note that here the variable pos might have a different name in your file. You may replace that accordingly.
