Imports: exp

Function Details

exponential_2param_neg(rate=None, i0=None, x=None, y=None)

Calculate the data for a standard two parameter decreasing exponential.

The y-values will be calculated based on the x-values.

Parameters:

• rate (float) - The exponential rate.
• i0 (float) - The initial intensity.
• x (numpy rank-1 float array) - The x-values at which to calculate the y-values.
• y (numpy rank-1 float array) - The data structure to store the y-values in.
