% defining myFunction for question 1
function f = myFunction(x)
f = tan(x).^2 + x -2;
end
% driver.m
% create funtion handler for myFunction
fun = @myFunction;
% initialize the given range with pi/10 step
r = -2*pi: pi/10 : 2*pi;
% use feval to evaluate fun in range r
result = feval(fun, r);
% Now plot the result

In MATLAB please Consider the nonlinear function: y = f(x) = x3 cos x a. Plot y as a function of x as x is varied between -67 and 67. In this plot mark all the locations of x where y = 0. Make sure to get all the roots in this range. You may need to zoom in to some areas of the plot. These locations are some of the roots of the above equation. b. Use the fzero...
Don't use fplot command. Matlab code. Write out code please, don't make it a screenshot. 2. Use the subplot command to make two plots of the function f(x) = (x + 1)(x - 2)(2x – 0.25) - et one graph for 0 < x <3 and the other for 3 < x < 6. Use a logarithmic scale for the y-axis. Include a plot title (for each subplot), and label both aris(for each subplot).

Please add comments line for matlab and show all step in paper, ASAP. Thanks in advance. 0.24 Hyperbolic sinusoids-In filter design you will be asked to use hyper bolic functions. In this problem we relate these functions to sinusoids and obtain a definition of these functions so that we can actually plot them (a) Consider computing the cosine of an imaginary number, i.e., use cos(x) 2 let j and find cos(x). The resulting function is called the hyper- bolic cosine...
Q: please solve using matlab code withe comment 1. Write the Matlab code to generate: x = cos(w1*t) + cos(w2*t); where, w1=7; w2=23; t = [0:0.005:2] 2. Plot the signal using sub plot a. in time domain b. in frequency domain 3) Sample the signal under different sampling conditions: a. Ts<1/2fm b. Ts=1/2fm c. Ts>1/2fm 4). Multiple plot: the signal sampled under sampling condition and the signal x a. in time domain b. in frequency domain c. Label and Title...
1. Write a Matlab function, piecewise (), that will calculate and return the value of the function f(x) defined by: 0<rS3 3<s5 e (x) -cos(3r) 2 sin(r) 2. Write a Matlab script to plot the function f(z) on the interval -3ss8. Ensure the output is sufficiently smooth by declaring z with enough data points. The plot should include the title My Piecewise Function, appropriate axis labels and grid lines. 1. Write a Matlab function, piecewise (), that will calculate and...
Please MATLAB for all coding with good commenting. (20) Consider the function f(x) = e* - 3x. Using only and exactly the four points on the graph off with x-coordinates -1,0, 1 and 2, use MATLAB's polyfit function to determine a 3' degree polynomial that approximates f on the interval (-1, 2]. Plot the function f(x) and the 360 degree polynomial you have determined on the same set of axes. f must be blue and have a dashed line style,...
