Values from a column selection index vector
selection2values Returns the actual chosen elements of a data from a
vector that indicates the chosen column. Therefor max(selectedElements) <=
max(size(Data)) && min(selectedElements) >= 1
Syntax: chosenValues = selection2values(Data, selectedElements)
Inputs:
Data: is the data where a selction was made on.
selectedElements: is a vector pointing to the column selected
Outputs:
the values at the selected column positions
Example:
DATA = [1, 2, 3, 4; 4, 5, 6, 7];
selectedElements = [1; 3];
values = selection2values(DATA, selectedElements); % returns [1; 6]
or
DATA = randn(500, 4); % data was given
selectedElements = randi(3, 500, 1); % selection was made
values = selection2values(DATA, selectedElements); % the actual values
that are wanted!
