Document Summary

Ginput: displays coordinates where a user clicked on a graph. Saving plots: file -> save as. Histogram two arguments: data set, followed by number of bins (default is 10: hist function, also functions for pie charts, box and whisker plots, search specialized plotting . 3_d surfaces: surf: fills in surface. 3-d surfaces: pseudo color plot: 2 d value represented by color, use pcolour. 3-d surfaces: contour plot if you want to just display lines that connect points of the same z elevation: additional examples: type demo in command window, scroll down to graphics. Vectors: indexing: process of extracting or inserting values in a vector, syntax: V(index) returns element(s) at location specified by index. V(index) = value replaces elements at specified locations. Numerical indexing: indexing vector can be any length of integers. All dimensions on either side of replacement instruction must be equal, or.
