evaluation postfix function taken postfix input format in string and return CMatrix object as a result

simplify string parsing functionality and encapsulate in in a separate file and make our main function clean

The function should get a matrix then evaluate one of the two cases:

• Evaluate multiply the matrix by itself according to power value.
• Evaluate the power of each item in the matrix.

For ex:
A =
1 2
3 4

A^2 =
7 10
15 22

A .^2 =
1 4
9 16

handling different error may happened and throw error massage and catch it
sample errors:
A = [1 2; 3]
B = 5 / 0
C = 3 * (2 + 4 +

The program should accept:

• Matrix in matrix.

For ex:
B = [4 5;6 7]
C = [8;9]
A = [1 2 3;B C]
or
A = [1 2 3;[4 5;6 7] [8;9]]
A =
1 2 3
4 5 8
6 7 9

• Expressions.
  -- Parse it and use Mathematical Expressions Functions.

For ex:
A = [1 2; 4 15/(2.1+10*sin(0.12))]
A =
1.0000 2.0000
4.0000 1.4266

Parse String mathematical expression and evaluate the operations through their functions and be aligned with Polish Notation issue.
for ex:
L = (1.2 + 3.4 - 5.6) / (2.1 * 3.2 + 4.6) - 12.1 * 3.1 + (1.2 + 5.2) ^ (4 / (3.2+5.6))

The function should get each single expression and evaluate it separately.

The function should get a matrix and evaluate the value of each item in the matrix

For ex:
A =
1 2 3
4 5 6

sin(A) =
0.84147 0.90930 0.14112
-0.75680 -0.95892 -0.27942

For now we will implement sine and cosine only.

Fix multiplication condition

Default Matrices are rand, eye, zeros and ones

These functions should get number of rows and columns then construct a matrix of this size and fill matrix items according to its type.

for ex:
// Random Numbers
D = rand(3,3)
D =
0.24757 0.74756 0.98016
0.69369 0.63851 0.72111
0.91013 0.58112 0.13993

D = eye(3,3)
D =
Diagonal Matrix
1 0 0
0 1 0
0 0 1

D = zeros(3,3)
D =
0 0 0
0 0 0
0 0 0

D = ones(3,3)
D =
1 1 1
1 1 1
1 1 1

The function should get a matrix and evaluate the value of each item in the matrix

For ex:
A =
1 2 3
4 5 6

log(A) =
0.00000 0.69315 1.09861
1.38629 1.60944 1.79176

The function should get a matrix and evaluate the root value of each item in the matrix

For ex:
A =
1 2 3
4 5 6

sqrt(A) =
1.0000 1.4142 1.7321
2.0000 2.2361 2.4495

Fix inverse function that produce nan matrix

Convert mathematical Infix form to Postfix
For ex:
5 + 4 * 3 - 2 => 5 4 3 * + 2 -

handle more edge cases in the code and throw string errors that describe what happens.

simplify the operator and functions for optimization.

The function should receive a Mathematical Expression then evaluate it according to its priorities.

For ex:
A = 5.5 + 12 * sin(0.4) + 2.2^4
A = 33.599
