Matlab Tutorial 3: Strings in Matlab


>> D{1,1}=123.23
>> D{1,2}='kalle'
We can of course also make the whole cell array from the beginning.
>> A={'Charles', 'Anderson', 23, 'football';'Gwen','Nolan',34, 'golf'}
A =
'Charles' 'Anderson' [23] 'football'
'Gwen' 'Nolan' [34] 'golf'

Different applicable commands to cell arrays can be found in the table below:

  • cell(m,n) Creates an empty m by n cell array.
  • celldisp(A) Displays all elements in the cell array A.
  • cellplot(A) Gives a graphical picture of the cell array A.
  • cell2struct(A,post,dim) Creates a structure, if dim=1, the information is read column wise to field 1 in the structure.
>> cellplot(A)% the result can be seen in figure below
Charles Anderson 23 football
Gwen Nolan 34 golf

We will also exemplify how cell2struct can be used. If the concept structure is not known from programming you will also have a possibility later on in the course to get to know the concept. Structure is a variable containing different fields. Think of it as a method of organizing the variable. Each field can be accessed by dot notation.

>> E=cell2struct(A,{'first_name','last_name','age','sport'},2)
 
% notice that dimension is now 2.
E =
2x1 struct array with fields:
first_name
last_name
age
sport
Display the different fields within the structure:
E(1)
ans =
first_name: 'Charles'
last_name: 'Anderson'
age: 23
sport: 'football'
E(2)
ans=
first_name: 'Gwen'
last_name: 'Nolan'
age: 34
sport: ’golf’

    go on …

    seems missing a ‘\’ before ‘n’ (new line escape character)
    Line: x= input(‘Give me a name !: n’,'s’); % skips a row
