How to find minimum value ,correspondings to a column ,in an output ?

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.

Excuse me but I do not undersatnd you. Which command should I write ?

[Steven Lord]

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
