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])
Print from the structure: To print from the structure, a disp function will show either the whole structure or a field. >> disp(package) item_no: 123 cost: 19.99
Example to change the line width from the default: For illustration, to change the line width from the default of 0.5 to 1.5: >> set(hl,'LineWidth',1.5) As long as the
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
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?
Gauss Elimination: The Gauss elimination technique consists of: Generating the augmented matrix [A b] Applying EROs to augmented matrix to obtain an upper trian
Example of Plotting from a Function: For illustration, the function can be called as shown below: >> y = [1:2:9].^3 y = 1 27 125 343 729
Finding sums and products: A very general application of a for loop is to compute sums and products. For illustration, rather than of just printing the integers 1 through 5, w
