MATLAB: How to convert an array to a one-line string

arrayconvertMATLABstring

At first I have two 3×3 arrays written in string form:
A = '[2, 3, 4; 5, 1, 8; 9, 1, 4]'
B = '[7, 5, 3; 5, 2, 3; 7, 1, 5]'
The first issue is to multiple these two matrices after converting them to numerical with str2num function. This part is clear and done. But after this operation, I need to convert the result matrix back to string (or char vector) and print it to a cell in app designer:
num2str(str2num(A) * str2num(B))
ans =
  3×10 char array
    '57  20  35'
    '96  35  58'
    '96  51  50'
The problem here is the result matrix has 3 rows, which leads to an error when printing it to a cell. MATLAB wants the variable to be a character vector (not a character array) when print in a cell. So I want this matrix to be transformed into the form that:
'57  20  35; 96  35  58; 96  51  50'
or
'57  20  35 96  35  58 96  51  50'
Thanks in advance.

Ercument - you could try using rehape to convert your numeric matrix into a single row
C = str2num(A) * str2num(B);
D = num2str(reshape(C', 1, []))
which should create the string 
'57  20  35 96  35  58 96  51  50'
