MATLAB: Task for generating a wave

sinesine wavewave

Can you suggest me some unique code for Sine wave

Best Answer

%Sine wave example

f=3; %frequency [Hz]

t=(0:1/(f*100):1);

a=2; %amplitude [V]

phi=0; %phase

y=a*sin(2*pi*f*t+phi); %formula

plot(t,y)

xlabel('Time') %label

ylabel('Amplitude') %label

title('Sine Wave)'); %Title

MATLAB: My plots appear very faint when I print the plots using Ms Word platform. Please How to make the thickness of the lines appear after printing? Thanks. THE ANSWER WORKS. HOWEVER, THE AXES STILL LOOK FAINT AND PORTIONS OF THEM DISAPPEARED. HOW PLS

 x=0:pi/10:2*pi;
plot(x, sin(x),'linewidth',4)
xlabel('Angles in Rad')

MATLAB: How to generate square wave in matlab

Make one period, then use repmat() to replicate as many times as you want.

% Now make one cycle with amplitude 1000 and 200 elements.
onePeriod = 1000 * [ones(1, 100), zeros(1, 100)];
% 200 elements is supposed to be 0.1 seconds so find out delta t.
dt = 0.1 / numel(onePeriod);
% Define number of cycles.
numCycles = 10;
% Copy this period that many times.
fullWaveForm = repmat(onePeriod, [1, numCycles]);
% Make time axis from 0 to 1 second.
t = dt * (0 : (numel(fullWaveForm) - 1));
% Now plot it.
plot(t, fullWaveForm, 'b-', 'LineWidth', 2);
FontSize = 20;
xlabel('Time (seconds)', 'FontSize', FontSize);
ylabel('Amplitude', 'FontSize', FontSize);
title('Square Wave With 10 Cycles', 'FontSize', FontSize);
grid on;
