Displaying expressions:
The good-looking function will show such expressions by using exponents; for illustration,
>> b = sym('x^2')
b =
x^2
>> pretty(b)
x
2
There are many plot functions in a MATLAB with names starting with "ez" which perform the essential conversions from symbolic expressions to numbers and plot them. For illustration, the function ezplot will draw a 2-D plot in the x-range from -2π to 2π, with the expression as the title. The expression
>> ezplot('x^3 + 3*x^2 - 2')
generates the figure as shown in figure.
The domain for the ezplot function can also be identified; for illustration, to change the x-axis to be from 0 to π, it is identified as a vector. The result is as shown in figure.
>> ezplot('cos(x)',[0 pi])
Passing arguments to functions: In all these functions examples faraway, at least one of the arguments was passed in the function call to be the value(s) of the equivalent inp
Built-in colormaps: The MATLAB has numerous built-in colormaps which are named; the reference page on colormap shows them. Calling the function colormap without passing any ar
Program to Counting in a while loop: The script initializes variable counter to 0. Then, in the while loop action, each and every time the user successfully enter a number, th
Expanding a function: The expand function will multiply out terms, and factor will do the opposite: >> expand((x+2)*(x-1)) ans = x^2 x-2 >> factor(ans)
Creating the structure Variables: Creating a structure variable can be accomplished by simply storing the values in fields by using assignment statements, or by using the stru
I have a frequency response data. How do I convert that to state space? I am given a 6 row and 3 column data (steady state). How do i convert that to state space model?
Illustration of gauss-jordan: Here's an illustration of performing such substitutions by using MATLAB >> a = [1 3 0; 2 1 3; 4 2 3] a = 1 3 0 2 1 3 4 2
Algorithm for expfn function: The algorithm for expfn function is as shown: receives the value of x as the input argument. Prints the value of exp(x). assigns a
Solving 2 × 2 systems of equations: However this may be easy in a MATLAB, in normal finding solutions to the systems of equations is not. The systems which are 2 × 2 are, thou
Examine exponential function: The algorithm for the main script program is shown below: Call a function eoption to show the menu and return the user's choice. Loop
