model_peak_center_intensity: model peak center

In MoseleyBioinformaticsLab/FTMS.peakCharacterization: Functionality for Detecting and Characterizing Peaks

model peak center

Description

use the derivative of the parabolic equation to find the peak center, and then put the center into the equation to find the intensity at that point.

Usage

model_peak_center_intensity(x, coefficients)

Arguments

x	the x-values to use (non-centered)
coefficients	the model coefficients generated from centered model

Details

The coefficients are generated using the linear model:

y = a + bx + cx^2

.

The derivative of this is:

y = b + 2cx

The peak of a parabola is defined where y is zero for the derivative.

x = -b / 2c

We can use this to derive where the center of the peak is, and then put the center value back into the equation to get the intensity.

Value

numeric
