Is it possible to store elements of a matrix raw as a string array in Matlab?

Is there any smart way to store elements of a matrix raw as a string array?

For example:

If A=[1 2 3; 4 5 6] a 2x3 matrix, str(1)='1 2 3' and str(2)='4 5 6'; a 1x2 array

Unfortunately, I don't think there's a way to make it workout syntactically exactly like you requested. I see two options:

  1. As Geoff mentioned str = cellstr(num2str(A)) will get the job done and you'll have to index it as str{1} (note that str(1) returns a cell array and not a string).

  2. If you want an array, you can just use str = num2str(A)

eg

>> num2str(A)
ans =
1  2  3
4  5  6
>> str(1,:)
ans =
1  2  3
>> str(2,:)
ans =
4  5  6

Kept as a vector, you'll have to access your string with str(1,:).

There is a way (whether it is smart or not) to convert the matrix to a cell array of strings:

>> str = cellstr(num2str(A));

str = 

'1  2  3'
'4  5  6'

Input matrix A is converted to an 2x7 array of characters (two spaces between each number) via num2str, and then we convert it to a cell array of strings via cellstr. The first string is accessed by str{1} and the second by str{2}.
