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
Illustrations of Variable number of output arguments: In the illustrations shown here, the user should actually know the type of the argument in order to establish how many va
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
Illustration of Logical vectors: Calling the function appears to return similar vector as simply vec > 5, and summing the result still works to determine how many elements wer
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
Functions to create special matrices: The MATLAB also has various functions which create special matrices. For illustration, the zeros function generates a matrix of all zeros
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
Built-in function for Differentiation: The MATLAB has a built-in function, diff that returns the differences between consecutive elements in a vector. For illustration, >>
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
Write a MATLAB function [d1, u1, l1, c1, r1] = NaiveGaussArrow(d, u, l, c, r) that takes as input the 5 vectors dened above representing A. This function performs Naive Gauss redu
