function [dataOUT] = normalize_data(dataIN)
|
|
%NORMALISE_DATA normalizes data by max of region
|
|
%
|
|
% Usage: [dataOUT] = NORMALISE_DATA(dataIN), where dataIN is a dataset
|
|
% loaded via the LOAD_MATLAB or LOAD_BRUKER function.
|
|
%
|
|
% The function will show the input data and offer two input fields, where
|
|
% the left and right borders of the maximum's region should be set.
|
|
% By pressing "Apply" the normalization will be executed and the graph
|
|
% changes to the normalized data.
|
|
% By pressing "Reset" the graph will return to show the original data.
|
|
% Exit the function by pressing "Done".
