# Matrix-Lib-for-C

  This a header file for C which gives varible like functionalities to 2D matrices.

  All functions will accept pointers as input and return pointer/value depending on function.

  The following are the propossed functions for this project,

  

 1)sum(X,Y) //Currently under the name of MsumV1.c

 

            Input

                  X -type(pointer to 2D array)

                  Y -type(pointer to 2D array)

                  

            Return

                  A pointer pointing to a 2D array containing the sum of X and Y.

 2)diff(X,Y)

 

            Input

                  X -type(pointer to 2D array)

                  Y -type(pointer to 2D array)

            Return

                  A pointer pointing to a 2D array containing the difference of X and Y.(i.e X - Y)

                  

 3)prod(X,Y)

 

            Input

                  X -type(pointer to 2D array)

                  Y -type(pointer to 2D array)

            

                     

            Return

                  A pointer pointing to a 2D array containing the product of X and Y.  

            

            Note:

                 * Dimensions of X and Y need to be compatible for multiplication.

         

  

  4)div(X,Y)

  

            Input

                  X -type(pointer to 2D array)

                  Y -type(pointer to 2D array)

            

           

            

            Return

                  A pointer pointing to a 2D array containing the divident of X and Y.

             

            Note: 

                 * Works as X * Y^-1{i.e - prod(X,inverse(Y))  }

                 * Divion by 0 may throw errors.

 

 

  5)inverse(X)

  

              Input

                    X -type(pointer to 2D array)

                    

              Return

                    A pointer pointing to a 2D array containing inverse of X.

                    

  6)transpose(X)

  

                Input

                     X -type(pointer to 2D array)

                Return

                     A pointer pointing to a 2D array that is the transpose of array X.

                     

  7)adjoint(X)

              

              Input

                    X -type(pointer to 2D array)

              Return

                    A pointer pointing to a 2D array containing the adjoint of X.

              

  8)rank(X)

            

            Input

                  X -type(pointer to 2D array)

            

     ***    Return

                  An Integer that is rank of the matrix X.

     ***

  

  9)reshape(X,g,h)

  

            Input

                 X -type(pointer to a 2D array)

                 g -type(Interger),row size of reshaped matrix

                 h -type(Interger),column size of reshaped matrix

            

            Return

                 A pointer pointing to the reshaped array.

                 

            Note:

                * Rehape is possible only if the dimensions of the input matrix and reshape dimensions are compatible.

                  i.e - Consider dimesions of X to be m x n.Then if X needs to be reshaped to g x h,

                        g x h = m x n MUST BE TRUE.
