Oyster_subincr_phases: Calculates proportion of phases in each sub-increment

Description

Function that takes the matrix of sub-increment positions and the matrix of phases and calculates the amount of pixels of each phase that is contained in each sub-increment based on pixelsize and phase characteristics. de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>

Usage

Oyster_subincr_phases(IncG, phasemat, pixelsize, phases)

Arguments

IncG

Matrix of X- and Y-coordinates of all interpolated sub-increments

phasemat

matrix of phases of each pixel sorted by X- and Y-coordinate of the pixel

pixelsize

size of pixels in the phase map in millimeter

phases

Matrix containing colour and trace element data of the phases in the XRF phase map

Value

A matrix of the amount of pixels for each phase found in every sub-increment

phase_mat

Matrix of amounts of pixels of each phase per sub-increment

Details

For every sub-increment, all pixels that cover area in the sub-increment are identified based on the pixel size of the phase map and the X- and Y-positions of the sub-increments. The amount of pixels of each phase in the sub-increment is saved in a new matrix of phases per sub-increment
