What is stem3 MATLAB?
stem3 plots each element in Z as a stem extending from the xy-plane and terminating at the data value. If Z is a column vector, stem3 plots all elements against the same x value at equally spaced y values. If Z is a matrix, stem3 plots each row of Z against the same y value at equally spaced x values.
Why stem command is used in MATLAB?
stem( Y ) plots the data sequence, Y , as stems that extend from a baseline along the x-axis. The data values are indicated by circles terminating each stem. If Y is a matrix, then stem plots all elements in a row against the same x value, and the x-axis scale ranges from 1 to the number of rows in Y .
What is stem in octave?
If y is a matrix, then each column of the matrix is plotted as a separate stem graph. In this case x can either be a vector, the same length as the number of rows in y , or it can be a matrix of the same size as y . The default color is “b” (blue), the default line style is “-” , and the default marker is “o” .
Why subplot is used in MATLAB?
subplot( m , n , p ) divides the current figure into an m -by- n grid and creates axes in the position specified by p . MATLAB® numbers subplot positions by row. subplot( m , n , p , ‘align’ ) creates new axes so that the plot boxes are aligned. This option is the default behavior.
What is difference between plot and stem?
Both plot and stem functions are used to represent a curve in MATLAB. The main point of difference between the two is that plot displays the continuous values for the curve. On the other hand, stem displays the discrete values of the points on the curve.
What is Axis command in MATLAB?
axis([xmin xmax ymin ymax]) sets the limits for the x- and y-axis of the current axes. axis auto sets MATLAB to its default behavior of computing the current axes’ limits automatically, based on the minimum and maximum values of x, y, and z data. You can restrict this automatic behavior to a specific axis.
What does stem command do?
Description. The stem (Scanning Tunneling Encapsulating Microscope) command is a tool for inserting instrumentation code, either user-supplied or default routines provided with stem, in subroutines.
What is grid MATLAB?
Description. The grid function turns the current axes’ grid lines on and off. grid on adds major grid lines to the current axes. grid off removes major and minor grid lines from the current axes.
Which is the default line style in stem3?
Stems are drawn from the height zto the location in the x-y plane determined by xand y. The default color is “b”(blue), the default line style is “-“, and the default marker is “o”. The line style can be altered by the linespecargument in the same manner as the plotcommand.
What happens when the fill argument is present in stem3?
If the “filled”argument is present the markers at the top of the stems will be filled in. Optional property/value pairs may be specified to control the appearance of the plot. If the first argument haxis an axes handle, then plot into this axis, rather than the current axes returned by gca.
How to make a 3 D stem plot?
Create a 3-D stem plot of cosine values between – π / 2 and π / 2 with a column vector input. stem3 plots elements of Z against the same x value at equally space y values. Create a 3-D stem plot of sine and cosine values between – π / 2 and π / 2 with a matrix input. stem3 plots each row of Z against the same y value at equally space x values.
How to make a stem in MATLAB MathWorks?
Use a dashed line style for the stem, set the marker symbols to stars, and set the color to magenta. To specify only two of the three LineSpec options, omit the third option from the character vector. For example, ‘*m’ sets the marker symbol and the color and uses the default line style.
