MATLAB Practice: Using version R2021b MATLAB code which tweaks the following code. close all x = 0: pi/100: 2 * pi; wave1 = sin (x * 3); wave2 = sin (x * 7) + cos (x * 8); plot (x, wave1, 'b-', x, wave2, 'r:'); legend ('wave 1', 'wave 2'); title ('Some Example Data Waveforms'); xlabel ('Angle'); ylabel ('Amplitude'); a. Use subplot(3,1,x) b. Draw “wave1” with stem function in subplot(3,1,1) with xlabel, ylabel and legend c. Draw “wave2” with stem function in subplot(3,1,2) with xlabel, ylabel and legend d. Draw “wave1” and “wave2” with stem function in subplot(3,1,3) with xlabel, ylabel, legend and title

in MATLAB, how can i program a nested for loop for variable pairs i and j to look like this: I =1  J=1 I =1  J=2 I =2  J=1 I =2  J =2 I =3  J =1 I =3  J =2

Need help in Matlab. How do I modify this program to produce eye shapes like the pink picture using scaling, rotating and translating? Thank you! figure(1) x(1:2,1)=[1;0]; plot(x(1), x(2),'*'); grid on; hold on; axis([-15 15 -15 15]); k=1; Inc=1; for j=1:Inc:360; x(1:2,k+1)=[cosd(Inc) -sind(Inc);sind(Inc) cosd(Inc)]*x(1:2,k); plot(x(1,k+1), x(2,k+1),'^'); k=k+1; %for j=1:Inc:360; %x(1:2,k+1)=[cosd(Inc) -sind(Inc);sind(Inc) cosd(Inc)]*x(1:2,k); %plot(x(1,k+1), x(2,k+1),'^'); %k=k+1; %pause(); end   for k=1:Inc:360; y1(1:2,k)=[1.5 0;0 3]*x(1:2,k); plot(y1(1,k),y1(2,k),'^') %for k=1:Inc:360; %y1(1:2,k)=[1.5 0;0 3]*x(1:2,k); %plot(y1(1,k),y1(2,k),'^') %pause(0.1); end   for k=1:Inc:360; y2(1:2,k)=[3 0;0 1.5]*x(1:2,k)+[7;5]; plot(y2(1,k),y2(2,k),'^') %for k=1:Inc:360; %y2(1:2,k)=[3 0;0 1.5]*x(1:2,k)+[7;5]; %plot(y2(1,k),y2(2,k),'^') %pause(0.1); end   for k=1:Inc:360; y3(1:2,k)=[3 0;0 1.5]*x(1:2,k)+[-7;5]; plot(y3(1,k),y3(2,k),'^') %for k=1:Inc:360; %y3(1:2,k)=[3 0;0 1.5]*x(1:2,k)+[-7;5];…

Use Matlab to write a function that calculates the area of a triangle given length of the three edges.

“The function negl3(n) = negl1(n) + negl2(n) is negligible.” What can you say about the function negl6(n) = negl4(n) – negl5(n)?

zero-pressure specific heat of dry air cp in kJ/(kg K) is given by: cp = 0.99403 + 1.671 × 10−4T + 9.7215 × 10−8T 2 −9.5838 × 10−11T 3 + 1.9520 × 10−14T 4 Here T is absolute temperature in K.Write a MATLAB script (a) to plot cp versus T  in the range between 0 to 1500 K, and                               (b) to determine the temperature that corresponds to a specific heat of 1.1 kJ/(kg K) with MATLAB polynomial functions. NOTE: 1. Axis titles and units are compulsory            2. The range the axes are to be set in such that the plot is visible in at least 70% of the plot canvass
