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,:) = []
Expanding a function: The expand function will multiply out terms, and factor will do the opposite: >> expand((x+2)*(x-1)) ans = x^2 x-2 >> factor(ans)
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
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
Replacing, Finding, and separating strings: There are numerous functions which find and replace the strings, or parts of strings, within the other strings and functions which
Image Processing: The Images are represented as grids, or matrices, of picture elements (known as pixels). In MATLAB an image usually is represented as a matrix in which each
Gauss, Gauss-Jordan elimination: For 2 × 2 systems of equations, there are well-defined, easy solution techniques. Though, for the larger systems of equations, finding solutio
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
Plotting from a Function: The following function creates a Figure Window as shown in figure, which shows various types of plots for similar y vector. The vector is passed as a
Example to change the line width from the default: For illustration, to change the line width from the default of 0.5 to 1.5: >> set(hl,'LineWidth',1.5) As long as the
Function used in sound files: The MATLAB has numerous other functions which let you read and play sound or audio files. In the audio files, sampled data for each audio channel
