Start MATLAB with uC

A programming language for smart Engineer

By Ashish  AC Nishad

Hello friend,

         MATLAB is a software package for high-performance numerical computation and visualization. It provide an interactive environment, graphics and animation.

MATLAB is used extensively in both academic and industry.  The purpose of this topic is to familiarize the beginner to MATLAB, by introducing the basic  features and commands of the program. Guess, it is no way a complete reference and the reader is encouraged to further enhance his or her knowledge of MATLAB by reading some of the suggested references.

             Beginner please installs the MATLAB software

 Here Now we start some plotting with the  help of  MATLAB .

1 Ex. - create a vector of x

values ranging from zero to , compute the sine of these values, and plot the

result.

x = 0:pi/100:2*pi;

y = sin(x);

plot(x,y)

Try it: t = 0:pi/10:2*pi;

plot(exp(i*t),'-o')

axis equal

Multiple Plots

t = 0:pi/10:2*pi;

[X,Y,Z] = cylinder(4*cos(t));

subplot(2,2,1); mesh(X)

subplot(2,2,2); mesh(Y)

subplot(2,2,3); mesh(Z)

subplot(2,2,4); mesh(X,Y,Z)

Tutorial fun for this month:

1. [X,Y] = meshgrid(-8:.5:8);

    R = sqrt(X.^2 + Y.^2) + eps;

     Z = sin(R)./R;

     mesh(X,Y,Z,'EdgeColor','black')

2. y = cos(x) from – π to π, we can first define the vector x with

components equally spaced numbers between – π and π, with increment, say 0.01.

     x=-pi:0.01:pi;

  y=cos(x);

  plot(x,y)

3. z=[0:02:1]’;

R=sin (3*pi*z)+2;

Cylinder(r),axis square
