MATLAB: How do i plot a graph between 3 variables?graph for x y and z 2dplots3d plotsgraphplotting data=xlsread('a.xlsx'); X=data(:,6); Y=data(:,5); for i=2:37 Z=(Y(i,1)-Y(i-1,1))/X(i,1); end Best Answer You need to index the variable Z,Z = zeros(size(X));for i=2:37 Z(i)=(Y(i,1)-Y(i-1,1))/X(i,1);endlplot3(X,Y,Z); Related SolutionsMATLAB: Help plotting with simple linespace and surf You were very close: you only forgot to change x to X and y to Y after you added meshgrid.x=linspace(0,2*pi);y=linspace(0, pi);[X,Y]= meshgrid(x,y);Z=sin(3*X).^2.*cos(4*Y).^3;surf(X,Y,Z)(next time, select your code and click the {}Code button to correctly format your code) MATLAB: How do i plot a 3d function and a 2d curve together m = 100 ; n = 100 ; x = linspace(-1,1,m) ; % define your range of xy = linspace(-1,1,n) ; % define your range of y [X,Y] = meshgrid(x,y) ; Z = X.^2/(X.^2-Y.^2) ; Z(X==Y) = 0 ; m = rand ; y = m*x ; surf(X,Y,Z)hold onplot3(x,y,zeros(size(x))) ; Related QuestionHow to plot itLoad .mat file variables without overwriting current variables of the same name
