data between data points

Hi,

I should say I'm a relative beginner to Labview. I am trying to convert from one file type to another.

I have x y data in array form. The original data was not generated with a uniform x interval, but the file I am converting to requires the x data to be evenly spaced from the start value to the end one. Does labview allow you to predict the y values at given x values i.e can a generate a new array with new x and y values where the x values are evenly spaced.

Any help would be greatly appreciated

Cheers

Dave

Hi Dave,

Try investigating the Interpolate & Threshold 1D Array in the Array Palette. You can specify the spacing yourself and iterate in a for/while loop to generate the proper vectors. This is "linear interpolation". You can have a look at spline interpolation too...

When you have worked a little with these, post what you've got if you're still stuck.
