how can I make waves from the equation and data value

I want to figure  waves from the equation and data value Aw ^ 2cos (wt) if I already have angular frequency data and time periods? And wanna plot maximum period vs. time period

[darova]

Did you try plot? Please attach your attempts

[Latifah Hanum]

No, actually I've never try MATLAB before, can you help me? In the picture

[Latifah Hanum]

the plot that I was hoping for was like in the picture, below with the data that was already there, but I didn't know how to code it

[Latifah Hanum]

clc

clear all;

close all;

A=

w = [6.11, 5.71, 5.07, 4.20, 3.15, 1.95, 0.66 , 0.66, 1.95, 3.16, 4.23, 5.12, 5.78, 6.19];

t = [1.03, 1.10, 1.24, 1.49, 1.99, 3.22, 9.51 , 9.50, 3.21, 1.99, 1.48, 1.23, 1.09, 1.02];

x0= A*cos(w*t);

figure (1)

subplot(2,2,1);

plot(t,x0);

axis([0 15 0 15])

xlabel('Time Period')

ylabel('Maximal Amplitude')

title('Seven Floor With Damping')

subplot(2,2,2);

plot(t,w);

axis([0 15 0 15])

xlabel('Time Period')

ylabel('Maximal Amplitude')

title('Seven Floor Without Damping')

but, the program is wrong, somebody can hepl me ? @darova

[Latifah Hanum]

Pls help me

[darova]

You can't get these graphs directly from

Maybe you should use fft?

[Latifah Hanum]

 can you help make the formula?

[darova]

But where is it? Something is missing

[Latifah Hanum]

what if I only have the function Y = Acos(wt). With the initial value of A is 0

[darova]

What is damping? Where is this variable

[Latifah Hanum]

This file

[Latifah Hanum]

I have an equation, Mx''-Cx'-Kx=MAw^2coswt

[Latifah Hanum]

Where M, C, K is matrix C is damping, without damping when C=0. the data above has been tabulated from the equation

[darova]

What about ode45? You have differential equation

[Latifah Hanum]

Wow, it's dificcult, but thank you, I try to learn it
