which command will create a plot of acceleration vs. time (i.e., a vector time on the x-axis and a vector acceleration on the y-axis)? in matlab

Assuming you have the time vector stored in variable t and the acceleration vector stored in variable a, you can create a plot of acceleration vs. time using the plot function in MATLAB as follows:

main.m
plot(t, a)
xlabel('Time')
ylabel('Acceleration')
title('Acceleration vs. Time')
80 chars
5 lines

This will create a plot with time on the x-axis and acceleration on the y-axis, with appropriate labels and a title.
