sprintf() with a %.2e format. Extract the portion of the result from the 'e' onward, discard the 'e', and remove the leading 0's from the exponent (the exponent will be either 2 or 3 digits depending on the operating system.) Make sure you keep a 0 if the overall exponent was exactly 0. Paste the resulting reformatted exponent on to the end of the formatted number, with 'x10' in-between.

T = cellstr( num2str( YourMatrix(:), '%.2e') );
Now apply the string manipulation to each string in the cell array T, T{1}, T{2} and so on. Afterwards put the strings together as needed.
Hint: regexprep() can help with the string processing.
