What does stem3 do in 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 row vector, stem3 plots all elements against the same y value at equally spaced x values. If Z is a column vector, stem3 plots all elements against the same x value at equally spaced y values.

How do you plot a stem in Matlab?

stem( X , Y ) plots the data sequence, Y , at values specified by X . The X and Y inputs must be vectors or matrices of the same size. Additionally, X can be a row or column vector and Y must be a matrix with length(X) rows. If X and Y are both vectors, then stem plots entries in Y against corresponding entries in X .

How do I change the size of a marker in Matlab?

Direct link to this answer

  1. You can change the marker size for a line plot by setting the “MarkerSize” property, either as a name-value pair or by accessing the “Line” object.
  2. Name-value pair:
  3. If you set this property as a name-value pair with the “plot” function, you must set it after all the x,y pairs.

How do you Discretize a plot in MATLAB?

To digitize, select “Add Points” from the “Digitization” menu. You may start digitizing points on the image at any time, but their transformed coordinated are not calculated until the reference data is complete. To see a digitized point’s transformed coordinate, right-click on a point. coordinates manually.

What is the difference between plot and stem?

The main point of difference between the two is that plot displays the continuous values for the curve. Think about drawing a graph of y= sin(x) using a pencil without removing its contact from paper. On the other hand, stem displays the discrete values of the points on the curve.

What is Xlabel in MATLAB?

xlabel( txt ) labels the x-axis of the current axes or standalone visualization. Reissuing the xlabel command replaces the old label with the new label. example. xlabel( target , txt ) adds the label to the specified target object. example.

How do you create a stem and leaf plot in Excel?

Use the following steps to create a stem-and-leaf plot in Excel.

  1. Step 1: Enter the data.
  2. Step 2: Identify the minimum and maximum values.
  3. Step 3: Manually enter the “stems” based on the minimum and maximum values.
  4. Step 4: Calculate the “leaves” for the first row.
  5. Step 5: Repeat the calculation for each row.

What is the default marker size in Matlab?

1/72 inch
Marker size. A scalar specifying the size of the marker, in points. The default value for MarkerSize is six points (1 point = 1/72 inch). Note that MATLAB draws the point marker (specified by the ‘.
