Document Summary

Scatter and plot allow you to plot multiple sets of datajust add it into the parenthesis (ex. plot(x, sin(x), x, cos(x))) Can plot functions by making y=f(x) (ex. y=sin(x)) To create grouped bars, use a matrix for the 2nd input where each row corresponds to a label. Histogram - visualization of the frequency of occurrence for certain values in a dataset. Use mean(mean(a)) to find the mean of the total matrix mean(a) - returns the column-by-column mean of a matrix median(a) - computes the median of a matrix unique(a) - creates an array of unique elements in a. Cell array - use {} to create an array of cells," but each cell can be any datatype. Csv - file is a table separated with commas deblank(x) - gets rid of blank spaces in a string cellarray{1,2} - test(1,2) = {[1,2,3]} - assigns 123 vector into the position in test.
