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
Example of Minimum and Maximum Value For matrices, the functions min and max operate column wise by the default: >> mat = randint(2,4,[1 20]) mat = 9 10 1
Use of logical vector: Determine how many elements in the vector vec were greater than 5, the sum function can be used on the resulting vector isg: >> sum(isg) ans =
Fliplr function: The fliplr function "flips" the matrix from left to right (in another words the left-most column, the first column, become the last column and so on), and the
Pie chart - plot functions: The MATLAB also has a function pie which will generate a pie chart. Calling the function with the form pie (vec) draws a pie chart, by using the pe
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
Built in recursive function in MATLAB: We have seen that the built-in function in MATLAB to compute factorials, termed as the factorial and we know how to implement the iterat
Sorting The Sorting is a process of putting a list in order; either in descending (maximum to minimum), or ascending (minimum to maximum) order. For illustration, here is a li
Matrix of Plots: The other function which is very useful with any type of plot is subplot that creates a matrix of plots in the present Figure Window. The three arguments are
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
Histogram: The histogram is a particular type of bar chart which shows the frequency of occurrence of the values within a vector. The Histograms use what are known as bins to
