WebbThe plot command is the basic command to generate 2D plot in Octave. Syntax. The basic syntax for the command is: plot(x,y) Optionally, we can provide many options to the command: plot(x,y,[options]) x and y are coordinates scalars or vectors. When the x and y are scalars the command plots a single point. WebbA marker is plotted at each point defined by the coordinates in the vectors x and y . The size of the markers is determined by s, which can be a scalar or a vector of the same length as x and y. If s is not given, or is an empty matrix, then a default value of 36 square points is used (The marker size itself is sqrt (s) ). university of otago postgraduateWebb13 feb. 2024 · Octave has some in-built functions for visualizing the data.
