Good day,
Could someone please help me on how to extract corresponding values of x-axis based on y-axis values?
x=[1,3,4,8,3,5,6,4,5,6,7,9]
y=[3,5,6,7,4,5,6,7,8,0,3,4]
I would like to extract the corresponding values of these elements; 5,6,7,4,5,6,7(values from y-axis) in x-axis.
I only know how to find a corresponding single value not multiple values.
Thanks

[z, zIdx] = mink(y,7);
xz = x(zIdx);

maybe use ismember:
idx = ismember(y, [5,6,74,5,67])
xvalues = x(idx)
P.S. sorry for the editing, I now read your problem correctly

The problem with this approach is that the last value of y will also be matched. I believe the OP is trying to isolate only the 7-element segment.

Thanks, Mara. It works almost percfectly except for the issue Adam mentioned. The approach also matched the last value of y.
Thank you both once again for your help
