IS Functions for Strings:
There are many functions for strings, that return logical true or false. The function isletter returns the logical true when the character is a letter of the alphabet. The function isspace returns the logical true when the character is a whitespace character. When strings are passed to such functions, they return the logical true or false for each and every element, or, in another words, each and every character.
>> isletter('a')
ans =
1
>> isletter('EK127')
1 1 0 0 0
>> isspace('a b')
0 1 0

Inverse of square matrix: The inverse is, hence the result of multiplying the scalar 1/D by each and every element in the preceding matrix. Note that this is not the matrix A,
Modular programs: In a modular program, the answer is broken down into modules, and each is executed as a function. The script is usually known as the main program. In orde
Changing Case: The MATLAB has two functions which convert strings to all uppercase letters, or all lowercase, known as the upper and lower. >> mystring = 'AbCDEfgh';
Cross Product: The cross or outer product a × b of two vectors a and b is defined only whenever both a and b are the vectors in three-dimensional space, that means that they b
