MATLAB: How do you get an arbitrary 1 dimensional line scan from a 2D Matrix

matrix manipulation

Hello,

say I had a NxN Matrix

Is there any easy way to plot a line scan from any arbitrary points (x1,y1) to (x2,y2)?

Example, attached is a 256×256 variable tdelt

I want a line profile of the data between the points (81,96) and (188,40)

Not sure How I can do this

Thanks!

Let x,y be your data.

[x,idx] = sort(x) ;
y = y(idx) ;
plot(x,y)

Use the interp1 (link) function:

x=linspace(0, 100, 100);
y = x.^2+6;
xi = interp1(y, x, 37)
xi =
