How to Graph in MATLAB

This video shows the simple process of plotting one or more equations in MATLAB with all the labels and legends. Fast and easy way to get all you need with MATLAB. Below I have the code attached. %% Simple guide to graph clc; clear x = -10:1:10; %parameters of the independent varianle x y = x + 3; %parameters of the variable y plot(x,y,'r'); %plot the variables listed in the equation xlabel('X'); %insert what you want the x label to be called ylabel ('Y'); %insert what you want the y label to be called title ('X vs. Y') %insert what you want the title of the plot to be legend ('Insert Function of first line'); %gives a legend where you can label each line on the graph %% Simple guide to graph 2 or more equations clc;clear; x1 = -10:1:10; %parameters of the independent varianle x1 x2 = -10:1:10; %parameters of the independent varianle x2 x3 = -10:1:10; y1 = x1 + 2; %equation one y2 = x2 - 2; %equation two y3 = 2*x3 + 1; %euqation three hold on %we need hold on to plot both equations on one graph plot(x1,y1,'r'); %plot the first equation with a red line plot (x2,y2,'b'); %plot second equation with a blue line plot (x3,y3, 'g'); %plot third equation with green line xlabel('X'); %insert what you want the x label to be called ylabel ('Y'); %insert what you want the y label to be called title ('X vs. Y') %insert what you want the title of the plot to be legend ('Insert Function of first line','Function or name of second line','insert function of 3rd line'); %gives a legend where you can label each line on the graph hold off %ends hold on for the graph %% Graph with plots vs equation clc;clear; x1 = -10:1:10; %parameters of the independent varianle x1 y1 = -3*x1+3; %equation one hold on %hold because we are ploting two things on one plot plot(x1,y1); %plot first equation x2 = [-7 -4 -1 0 2 5 7]; %given plot data for x y2 = [ 20 14 6 3 -2 -10 -15]; %given plot data for y plot (x2,y2,'redo'); %plot the given data with red circles for the points hold off %hold off title('insert title of the plot') %title of the plot xlabel('x') %x label ylabel('y') %y label legend('equation','Given data') %legend for equation one and the given data
