Calculate a slope with a 1D Array instead of a 2D Array.

[summer]

In this vi, I would like to calculate for every Y (50 different amplitudes and 60 different times) the slope of the Ys according to the amplitude differences: Y(i+1)-Y(i)/X(i+1)-X(i) (X is the amplitude). Y is a 2D Array, how could I do this if Y is a 1D Array?

Wire both 1-d arrays into a for loop set to go N-1 iterations, disable
indexing, index out i and i+1, subtract, subtract and divide, then enable
indexing the output so it will form the output 1d array. Your result will
necessarily have one less point than your input arrays.

Hi Asimpleman,

Thanks a lot for your help. Well, I'm a simple woman who has got problems with Labview. I've tried to follow your explanations, but I must have done something wrong.
