TransposeData

void TransposeData (void *dataArray, int dataType, int numberOfPoints, int numberOfChannels);

Purpose

Transposes a two–dimensional array of the specified data type.

This function is especially useful for separating the data from a multi–channel scanning operation into separate channels. For example, if you had an array of data from 5 scans of channels A through C in the following form:

A1 B1 C1 A2 B2 C2 A3 B3 C3 A4 B4 C4 A5 B5 C5

Transposing the data would yield the following array in which the data from each channel is stored contiguously:

A1 A2 A3 A4 A5 B1 B2 B3 B4 B5 C1 C2 C3 C4 C5

Parameters

Input
Name Type Description
dataArray void * Pass the array of data to transpose.
dataType integer Pass the data type of the elements in the array.
numberOfPoints integer Pass the total number of points in the data array.
numberOfChannels integer If the data was generated by a series of multi–channel scans, then pass the number of channels in the data. This is the same as the number of columns in the data.

Return Value

None.
