Differentiation:
The derivative of a function y = f(x) can be written as follows
or f '(x) and is defined as the rate of change of the dependent variable y with respect to x. The derivative is the slope of line tangent to the function at given point.
The MATLAB has a function polyder that will find the derivative of a polynomial. For illustration, for the polynomial x3 + 2x2 - 4x + 3, that would be represented by the vector
[1 2 - 4 3], the derivative is found by:
>> origp = [1 2 -4 3];
>> diffp = polyder(origp)
diffp =
3 4 -4
that shows that the derivative is the polynomial 3x2 + 4x - 4. The function polyval can be used then to find the derivative for certain values of x; for illustration for x = 1, 2, and 3:
>> polyval(diffp, 1:3)
ans =
3 16 35
The derivative can be written as folows
and can be approximated by difference equation.
Empty Vectors: An empty vector or in another words, a vector which stores no values, can be generated using the empty square brackets: >> evec = [] evec = [] >> lengt
Dimensions - matrix: The size and length functions in the MATLAB are used to find array dimensions. Length function returns the number of elements in the vector. The size func
Print an imaginary number: To print an imaginary number, the function disp will show both parts automatically: >> disp(z1) 4.0000 + 2.0000i The function fprint
Labels and Prompts: The script loads all the numbers from file into a row vector. It then splits the vector; it stores the initial element that is the experiment number in a v
Complex numbers: A complex number is commonly written in the form z = a + bi here a is known as the real part of the number z, b be the imaginary part of z, and i is √-1
sprintf function: The sprintf function works precisely like the fprintf function, but rather than printing it generates a string. Here are some illustrations in which the outp
Common form of the switch statement: The common form of the switch statement is as shown below: switch switch_expression case caseexp1 action1 case cas
Example of Symbolic Expression When there is more than one variable, the MATLAB selects which to solve for. In the illustration below, the equation ax 2 + bx = 0 is solved. Th
Structure Consisting of the Fields A MATLAB can also solve the sets of equations. In this illustration, the solutions for x, y, & z are returned as a structure consisting of th
Changing Dimensions: In addition to transpose operator, the MATLAB has some built-in functions which change the dimensions or configuration of matrices, involving fliplr, resh
