Matrix
A Matrix is a rectangular array or table of numbers, symbols or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object. For example, is a matrix with two rows and three columns.
Script:
clc
A=[2 4 6; 7 8 9;]
B=[11 9; 7 5; 3 1;]
C=A*B
D=B*A
Script Analysis:
The above code where clc refers to clear all. clc clear all texts from the command window. Then, the array of A[] refers a 2x3 array and B[] refers a 3x2 array. The resulting Matrix solution for C is a 2x2 matrix and D is a 3x3 Matrix. The solution is shown below.
Solving Equation
syms a b c x
a=5;
b=7;
c=3;
%The equation is 5x^2+ 7x + 3 = 0
eqn= a*x^2 + b*x + c == 0
x=solve(eqn)
Loop
%code 3: Sum of 1 to 10 using loop
clc %Clear all
n=10;
sum=0;
for i=0: 1 :n
sum=sum+i;
end
SUM=sum %display sum
