MATLAB: Cell array/Character array to string

cell arrayscharstrings

I have generated a cell array of characters eg. cea={'8' '_1' '9' '_3'}. I need this to be converted to a string '8_19_3' for labelling a figure.

I have converted to a character array using cha=char(cea), in this example it will be a 4×2 array. Then the correct string can be given by str=[cha(1,:),cha(2,:),cha(3,:),cha(4,:)] (except this has unwanted spaces).

However the length of the character array can vary in a loop. Using str=[cha(1:length(cha),:)] does not give the same string as I think it should.

Why is this and is there a better way to go about doing it?

Thanks

cea={'8' '_1' '9' '_3'}
str = strcat(cea{:})

str = [cea{:}];

MATLAB: Does STRMATCH in MATLAB cause an error for a cell array containing a numeric value

In this example:

str = 9;
strs = strvcat('This is a string array','with two rows');
ind = strmatch(str,strs);

the normal STRMATCH is used, since the first input is not a cell array. In this case, 9 could be used as an ASCII value, and converted to a tab character. That character can then be compared with the other strings.

In this example:

str ={9};
strs = strvcat('This is a cell array of strings','with two rows');
ind = strmatch(str,strs);

@CELL/STRMATCH will be used, since the first input is a cell array. In this case, the code checks that the cell array contains strings, and converts it to a char array:

if iscellstr(str), str = char(str); end

Cell arrays of strings are special cases of cell arrays, which are commonly used to store strings together which have different lengths, and there are many instances where cell arrays of strings and strings can be used interchangeably. However, {9} is not a cell array of strings, so it is not converted to a character array, which leads to the error being thrown by this code:

if ~ischar(str) | ~ischar(strs)
    error('Requires character array or cell array of strings as inputs.')
end

MATLAB: How to retrieve original characters from string array/character array after receiving from RS232 serial port

1024 x 5 = 5120 elements, so there's one too many in your A array. Remove whichever it is:

 A(indexofextraelement) = [];

Then reshape your array:

 reshape(A, 1024, 5)
