% readExperimentalData : Read in the pendulum experiment data from an Excel

% xlsread by default returns the matrix of numeric data starting at the top
% left hand corner of Sheet 1 of the workbook.  When more output arguments
% are supplied it will also return the text data (here column headings) and
% the raw data (both text and numeric data returned as a cell array of
% strings).  The general form of a call to xlsread is:
% [numericData, textData, rawData] = xlsread(inFileName,<more options>);
% where <more options> are described by 'help xlsread' or 'doc xlsread'

% Here we are just interested in the numeric data so only call with a
% single output argument:
numericData = xlsread(inFileName);

% Extract the columns of the numeric data array into fields of a structure.
res.Time = numericData(:,1);
res.Position = numericData(:,2);
res.Velocity = numericData(:,3);
