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,:) = []
Calling of Function polyval: The curve does not appear very smooth on this plot, but that is as there are only five points in the x vector. To estimate the temperature
Plotting File data: It is frequently essential to read data from a file and plot it. Generally, this entails knowing the format of the file. For illustration, let us suppose t
Function fieldnames - structure functions: The function fieldnames will return the names of the fields which are contained in the structure variable. >> pack_fields = fiel
True color matrice: The true color matrices are the other way to represent images. The true color matrices are 3-dimensional matrices. The first two coordinates are the coordi
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
7.13
Structures: The Structures are data structures which group together values which are logically related in what are known as the fields of structure. The benefit of structures
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
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)
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
