y = pdf('name',x,A) returns the probability density function (pdf) for the one-parameter distribution family specified by 'name', evaluated at the values in x. y = pdf(pd,x) returns the probability density function of the probability distribution object, pd, evaluated at the
Notice that the usual vector product X Y is unde ned. The Matlab object ones(m,n) is useful if you want to add or subtract a constant from each element in a vector. ones(m,n) is an m-by-n matrix of ones. Using the vector X from the last example, you write the expression X + 2 as follows in Matlab notation. X + 2 * ones(1,3).

Loading Generation of random variables with required probability distribution characteristic is of paramount importance in simulating a communication system.
It has since grown into a high-performance language for technical computing. MATLAB integrates computation, visualization, and programming in an easy-to-use en- vironment, and allows easy matrix manipulation, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with
Create a standard normal distribution object. pd = makedist('Normal'). pd = NormalDistribution Normal distribution mu = 0 sigma = 1. Specify the x values and compute the pdf. x = -3:.1:3; pdf_normal = pdf(pd,x);. Plot the pdf. plot(x,pdf_normal,'LineWidth'
Basic Overview. To use the 'plot' function in Matlab, you should first make sure that the matrices/vectors you are trying to use are of equal dimensions. For example, if I wanted to plot vector X = [3 9. 27] over time, my vector for time would also need to be a 1x3 vector (i.e. t = [1 2 3]). • Syntax. To plot the example vectors above
UPDATE: In newer versions of MATLAB the hist function is no longer recommended. Instead, you can use the histcounts function like so to produce the same figure as above: data = [1 2 3 3 4]; N = histcounts(data, 'BinLimits', [0 10], 'BinMethod', 'integers', 'Normalization', 'pdf'); plot(N); xlabel('Integer value')
1. INTRODUCTION. Creating plots of data sets and functions is very useful for engineers and scientists. You can use plots to present results for papers and presentations or to visually search for approx- imate solutions to problems. MATLAB has a rich set of plot- ting commands. In this chapter, we describe MATLAB's.

mathematical equations with graphics is an enjoyable and very efficient way of learning math- ematics. Being able to plot mathematical functions and data freely is the most important step, and this section is written to assist you to do just that. 2.2.2 Creating simple plots. The basic MATLAB graphing procedure, for example in
