plotImpulses:

consumes the Propulsion Impulse Matrix and the Braking

Impulse Matrix. Download the ‘barwitherr.m file from Canvas. This function

plots the impulses in the same style as the above figure using the bar chart

with error bars.

barwitherr

function takes two parameters:

first parameter – 2 X 5 matrix with the

std deviations

of the data

first row - each column is

std deviation

of

propulsion impulses

across all participants

second row - each column is std deviation of

braking impulses

across all participants

second parameter – 2 X 5 matrix with the

averages

of the data

first row - each column is

average

of

propulsion impulses

across all participants

second row - each column is

average

of

braking impulses

across

all participants

You can read the documentation for the bar chart for further information.

You must label your x-axis ticks “Propulsion” and “Braking” corresponding

with the positive and negative data points. You must include the legend for

“Baseline”, “Slow FTM”, “Fast FTM”, “Slow ATM”, and “Fast ATM”. Your Y-axis

must be labeled “Impulses”. Your function should return the plots properties

which can be created by wrapping your call to barwitherr inside of the get()

function.

For Example:

var_name = get(plot(x,y))
