Hello,
I have a question about a code. My code creates an output .txt file with two columns, (let's say x the 1st column and y the 2nd column) and plot the x-y plot. I am using "min(y)" in order to find the minimum value of y column. I would like to prind on my plot the x value that correspont to the minimum value of y column.
Could you please help me?

The second output from the min function will help you retrieve the corresponding element of x.

Ran in:
x = randi(10, 1, 8)
x = 1×8
6 2 9 8 7 4 5 7
y = x.^2
y = 1×8
36 4 81 64 49 16 25 49
[value, loc] = min(y)
value = 4
loc = 2
x(loc)
ans = 2
