Example: Load from File and Plot Data:
As illustration, a file known as timetemp.dat stores two lines of data. The first line is the time of the day, and the next line is the recorded temperature at each of those times. The first value of 0 for the time presents midnight. For illustration, the contents of the file may be:
0 3 6 9 12 15 18 21
55.5 52.4 52.6 55.7 75.6 77.7 70.3 66.6
The script below loads the data from the file into a matrix known as the timetemp. It then separates the matrix into vectors for the time & temperature, and then plots the data by using black + symbols.
Running the script generates the plot seen in figure:
Note that it is difficult to see the point at time 0 as it falls on the y-axis. The axis function can be used to change the axes from the defaults as shown
Implement a MatLab function to calculate y. The function should take two input arguments 1) A vector of parameters In the above example this would be of length 3, the first
-The program should run always until the user enters -1 to exit from the program. - In the main, you should ask user to input any angles in degrees (Ad) and an integer number (N).
The circuit diagram of an active filter is shown below. (a) Determine an expression for the transfer function of the filter. (b) Hence find an expression for the frequency res
A filter described by the equation: y(n) = x(n) + x(n-1) + 0.9 y(n-1) - 0.81 y(n-2) (a) Find the transfer function H(z) for the filter and find the poles and zeros of the fil
Strings: The MATLAB also handles strings that are a sequence of characters in single quotes. For illustration, using the double function on a string will represent the equival
Format command: The format command can be used to control the spacing between the MATLAB command or expression and the outcome; it can be either compact or loose. >> format
I need this task to be done with discription of matlab coding.
Create a function using mat lab to generate a sinusoidal signal. The parameters of the signal should have an Amplitude = 100, frequency = 100Hz, initial phase = 0, sample rate = 50
Example of Printing vectors: For vectors & matrices, even though formatting cannot be specified, the disp function may be simpler to use in common than fprintf as it displays
Simple Related Plot Functions: The other functions which are useful in customizing plots are the figure, clf, hold, leg-end, and grid. The short description of such functions
