It is required to develop a program to do Matrix operations. The program
use a defined string format to represent the matrix in the user input and
output sections. For the following matrix:

for example :

|10 2.13 3 |
|-5 0 4 |
|16.5 1 8 |


the string representation of the Matrix is :
[10 2.13 3;-5 0 4;16.5 1 8]
