Create a 3-D stem plot of cosine values betweenandwith a row vector input.

figure X = linspace(-pi/2,pi/2,40); Z = cos(X); stem3(Z)

stem3plots elements ofZagainst the sameyvalue at equally spacexvalues.

Create a 3-D stem plot of cosine values betweenandwith a column vector input.

figure X = linspace(-pi/2,pi/2,40)'; Z = cos(X); stem3(Z)

stem3plots elements ofZagainst the samexvalue at equally spaceyvalues.

Create a 3-D stem plot of sine and cosine values betweenandwith a matrix input.

figure X = linspace(-pi/2,pi/2,40); Z = [sin(X); cos(X)]; stem3(Z)

stem3plots each row ofZagainst the sameyvalue at equally spacexvalues.

Create a 3-D stem plot and specify the stem locations along a curve. Useviewto adjust the angle of the axes in the figure.

figure X = linspace(-5,5,60); Y = cos(X); Z = X.^2; stem3(X,Y,Z) view(-8,30)

XandYdetermine the stem locations.Zdetermines the marker heights.

Create a 3-D stem plot with matrix data and specify the stem locations in thexy-plane.

figure [X,Y] = meshgrid(0:.1:1); Z = exp(X+Y); stem3(X,Y,Z)

XandYdetermine the stem locations.Zdetermines the marker heights.

Create a 3-D stem plot of cosine values betweenandand fill in the markers.

X = linspace(-pi,pi,40); Z = cos(X); stem3(Z,'filled')

Create a 3-D stem plot of cosine values betweenand. Use a dashed line style for the stem, set the marker symbols to stars, and set the color to magenta.

figure X = linspace(-pi,pi,40); Z = cos(X); stem3(Z,'--*m')

To specify only two of the threeLineSpecoptions, omit the third option from the character vector. For example,'*m'sets the marker symbol and the color and uses the default line style.

Create a 3-D stem plot and specify the stem locations along a circle. Set the stem to a dotted line style, the marker symbols to stars, and the color to magenta.

figure theta = linspace(0,2*pi); X = cos(theta); Y = sin(theta); Z = theta; stem3(X,Y,Z,':*m')

XandYdetermine the stem locations.Zdetermines the marker heights.

Create a 3-D stem plot of cosine values betweenand. Set the marker symbols to squares with green faces and magenta edges.

figure X = linspace(-pi,pi,40); Z = cos(X); stem3(Z,'Marker','s',...'MarkerEdgeColor','m',...'MarkerFaceColor','g')

Specify the axes for a 3-D stem plot.

Define vectorsX,YandZ.

X = linspace(-2,2,50); Y = X.^3; Z = exp(X);

Create a figure with two subplots and return the handles to each axes,s(1)ands(2). Plot a 3-D stem plot in the lower subplot by referring to its axes handle,s(2). For comparison, plot a 2-D stem plot in the upper subplot by referring to its axes handle,s(1).

figure s(1) = subplot(2,1,1); s(2) = subplot(2,1,2); stem(s(1),X,Z) stem3(s(2),X,Y,Z)

Create a 3-D stem plot and return the stem series object.

X = linspace(0,2); Y = X.^3; Z = exp(X).*cos(Y); h = stem3(X,Y,Z,'filled');

Change the color to magenta and set the marker face color to yellow. Useviewto adjust the angle of the axes in the figure. Starting in R2014b, you can use dot notation to set properties. If you are using an earlier release, use thesetfunction instead.

h.Color ='m'; h.MarkerFaceColor ='y'; view(-10,35)
