This will work, but cannot figure out how the same can be done via findloc:

Hello

Is there a way to find the indices in array where a condition is satisfied and then extract those values. The equivalent in Matlab/Scilab:

values = x(find(x > 4.7)) where x is an array ...

Managed to get the plot working, just followed you original syntax:

iw = winio@('%mn[Export]&',export_cb ...

Added the routines to my existing code and it works fine to compute the intersections, but having issues getting it plotting symbols ...

Hello

Quick query. How do you set tight limits on an axis? Currently a plot goes from 0 to 105 on x-axis but I need it to be tight in the range 0-100. An example code would be useful.

Thanks

Hi Kenneth,

Thanks for the pointer, not sure how to get the syntax working. Just adding export_image@(Riemann1.jpg') just makes a blank image file?

Hi John

Thanks for the ideas to test. Yes the curves are defined as arrays of x,y values and not functions.

I would think it logical to look for a small region to test an approximation, where a ...

Hello,

Is there a way to calculate the intersections of two different curves given the data of two arrays, (x1, y1) and (x2, y2)?

Thanks

Many thanks Kenneth! That worked fine with the Clearwin usage. Will have to study that more.

Haven't had a thorough look yet, but can the plot be easily saved or exported to an image file?

Thank ...
