Function cellplot - Cell array:
The function cellplot place a graphical display of the cell array in a figure Window; though, it is a high-level view and fundamentally just displays similar information as typing the name of the variable (exmple, it wouldn't display the contents of the vector).
Also, most of the functions and operations on arrays which we seen work with the cell arrays. For illustration, here are several related to dimensioning:
>> length(cellrowvec)
ans =
4
>> size(cellcolvec)
4 1
>> cellrowvec{end}
hello
It is not possible to delete an individual element from the cell array. For illustration, assigning an empty vector to a cell array element does not delete the element, it merely replaces it with the empty vector:
>> cellrowvec
mycell =
[23] 'a' [1x5 double] 'hello'
>> cellrowvec{2} = []
[23] [] [1x5 double] 'hello'
Though, it is possible to delete the whole row or column from a cell array by assigning the empty vector (Note: use parentheses instead of curly braces to refer to the row or column):
>> cellmat
mycellmat =
[ 23] 'a'
[1x5 double] 'hello'
>> cellmat(1,:) = []
Function rmfield - structure: The function rmfield eliminates a field from the structure. It returns a new structure with field eliminated, but does not modify the original st
Example of Menu driven modular program: As an illustration of such a menu-driven program, we will write a program to discover the constant e. The constant e, known as the n
Example of Exponential function modular program: In order to view the distinction in the approximate value for e as n increases, the user kept choosing Limit & entering larger
Function used in binary search: The function below implements this binary search algorithm. It receives two arguments: the sorted vector and a key (on the other hand, the func
Subfunctions: Though, it is possible to have more than one function in a given M-file. For illustration, if one function calls the other, the first function would be the prima
Forward elimination: In forward elimination, we want to obtain a 0 in the a 21 position. To accomplish this, we can alter the second line in the matrix by subtracting from it

Example of Plotting from a Function: For illustration, the function can be called as shown below: >> y = [1:2:9].^3 y = 1 27 125 343 729
Use of built-in colormaps: MATLAB has built-in colormaps, it is also possible to generate others by using combinations of any colors. For illustration, the following generates
Example of Gauss-jordan: For a 2×2 system, this would results and for a 3 × 3 system, Note that the resulting diagonal form does not involve the right-most col
