+# MatrixMania
+
+This Package contains a few fundamental function which can be used for **matrices**.
+
+## Functions:
+
+- matmul function
+- transpose function
+- rot_2D function
+
+## matmul function:
+
+This function calculates the matrix multiplication with 2 matrices. 
+It also checks if the matrices are compatible for multiplication.
+
+**Example:**
+
+```
+matrix_a =  [[3, 4, -1, 4],
+             [-2, 2, 5, 1]]
+             
+matrix_b =  [[1, 3, -2],
+             [2, 5, 1],
+             [-1, 4, -4],
+             [2, 3, 6]]
+             
+matrix_c = matmul(matrix_a, matrix_b)
+print("matrix c:")
+print(tabulate(matrix_c))
+```
+
+**Result:**
+
+```
+matrix c:
+--  --  --
+20  37  26
+-1  27  -8
+--  --  --
+```
+
+
+## transpose function:
+
+This function transposes a matrix.
+
+**Example:**
+
+```
+matrix = [[1, 2, 3],
+          [4, 5, 6]]
+          
+new_matrix = transpose(matrix)
+print("transposed matrix:")
+print(tabulate(new_matrix))
+```
+
+**Result:**
+
+```
+transposed matrix:
+-  -
+1  4
+2  5
+3  6
+-  -
+
+```
+
+## rot_2D function:
+
+This function returns the rotation matrix for a given angle.
+
+**Example:**
+
+```
+theta = math.pi / 2
+R = rot_2D(theta)
+
+print("rotation matrix for 90°:")
+print(tabulate(R))
+```
+
+**Result**
+
+```
+rotation matrix for 90°:
+-----------  ------------
+6.12323e-17  -1
+1             6.12323e-17
+-----------  ------------
+```
