How do you plot a discrete sequence in Matlab?

How do you plot a discrete sequence 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 you plot a discrete value?

1. Column Charts. The most commonly used chart type for discrete data is the column chart.
2. Bar Charts. You also can use bar charts for discrete values.
3. Pie Charts. Pie charts also work well for displaying discrete data, as all the values combined equal 100 percent of the total.
4. Histograms.

How do you plot points on a graph in Matlab?

Create Line Plot with Markers

1. Add Markers to Line Plot. Copy Command. Create a line plot.
2. Specify Marker Size and Color. Copy Command.
3. Control Placement of Markers Along Line. Copy Command.
4. Display Markers at Maximum and Minimum Data Points. Copy Command.
5. Revert to Default Marker Locations. Copy Command.

How do you write a discrete function in Matlab?

The syntax for creating discrete-time models is similar to that for continuous-time models, except that you must also provide a sample time (sampling interval in seconds). H = z – 1 —————— z^2 – 1.85 z + 0.9 Sample time: 0.1 seconds Discrete-time transfer function. y [ k ] = 0 . 2 x [ k ] .

How do you input a discrete signal in Matlab?

At the MATLAB command line, type dsp_examples_yout . The first column of the matrix is the fast signal (Ts=1). The second column of the matrix is the slow signal (Ts=2). The third column is the sum of the two signals.

How do you write discrete TF in Matlab?

sys = filt(num,den) creates a discrete-time transfer function sys with numerator(s) num and denominator(s) den . The sample time is left unspecified ( sys. Ts = -1 ) and the output sys is a TF object. sys = filt(num,den,Ts) further specifies the sample time Ts (in seconds).

What is the discrete function?

a discrete function is one where a domain is countable (this will be shown as a bunch of points that are not connected together) and which meets the requirement of a function (each input has at most one output). In discrete functions, many inputs will have no outputs.

How do you plot in MATLAB?

Most Matlab plot functions simply plot a pair of vectors as X and Y coordinates. You can assemble those vectors in any fashion you want, including by concatenating vectors representing different functions over different ranges, such as the ranges and functions comprising a piecewise function.

What is the plot command for MATLAB?

Plot command. In MATLAB you create a two dimensional plot using the plot command. The most basic form is. plot(x, y) where x and y are vectors of the same length containing the data to be plotted. Plot the function y = sin(2 pi x) for x in the interval [0, 1] using 401 equally spaced points.

What is discrete data in math?

Discrete data is information that can be categorized into a classification. Discrete data is based on counts. Only a finite number of values is possible, and the values cannot be subdivided meaningfully. For example, the number of parts damaged in shipment.
