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. Similar to rand, either one argument can be passed (that will be both the number of rows and columns), or two arguments (at first the number of rows and then the number of columns).
>> zeros(3)
ans =
0 0 0
>> zeros(2,4)
0 0 0 0
Creating Customized strings: There are many built-in functions which create customized strings, including blanks, char, and sprintf. We know that the char function can be u
Function fopen - file function: The permission string in the call to the fopen function identifies that the file is opened for writing to it. Just as when reading from a file,
Illustration of logical built-in functions: The function find returns the indices of a vector which meet certain criteria. For illustration, to find all the elements in a vect
Illustration of Labels and prompts: The program below prompts the user for endpoints (x1, y1) and (x2, y2) of a line segment, and computes the midpoint of the line segment, th
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, >>
5 p2+8p+15, 3 p2-3p-18, 12 p2-p-30
Strcat function - Concatenation : The strcat function, though, will eliminate the trailing blanks from strings before concatenating. Note that in these illustrations, the trail
Referring to and Modifying the Matrix Elements: To refer to matrix elements, the row and then the column indices are given in parentheses (always the row index initially and t
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
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
