Using Functions with the Vectors and Matrices:
As MATLAB is written to work with the vectors and matrices, the whole vector or matrix can be passed as an argument to the function. MATLAB will compute the function on every element, and return as a result the vector or matrix with similar dimensions as the original. For illustration, we could pass the vector below, vec, to the abs function in order to get the absolute value of each and every element.
>> vec = -3:4
vec =
-3 -2 -1 0 1 2 3 4
>> abs(vec)
ans =
3 2 1 0 1 2 3 4
The original vector vec has 8 elements, and as the abs function is computed for every element, the resulting vector also has 8 elements.
This would also be the case for matrices:
>> mat = randint(2,3,[-5,5])
mat =
-5 -1 0
3 5 -1
>> abs(mat)
5 1 0
3 5 1
User input in the while loop: Here is an illustration of running this script: >> readonenum Enter a positive number: -5 Invalid! Enter a positive number: -2.2
Recursive Functions: The Recursion occurs whenever something is defined in terms of itself. In the programming, a recursive function is a function which calls itself. The Recu
User-defined functions: Therefore, although many functions compute and return values, some do not. A few functions rather merely accomplish a task. Regardless of what type of
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
Illustration of a recursive function: illustration is of a recursive function which does not return anything, but simply prints. The below function prtwords receives a sentenc
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
Error-checking for integers: illustrations of running this script as shown below: >> readoneint Enter an integer: 9.5 Invalid! Enter an integer: 3.6 Invalid
Example of Recursive functions: This definition is recursive as a factorial is defined in terms of the other factorial. There are two parts to any recursive definition: the co
Minimum and Maximum Value The MATLAB has built-in functions for numerous statistics. For illustration, min and max to find the minimum or maximum value in a data set. >> x
Plot types: Besides plot and bar, there are another plot types like stem plots, histograms, stem plots, area plots and pie charts, and also other functions which customize the
