For each of the operations (Addition, Subtraction, Multiplication, Determinant, Transpose and Inverse), make a function in addition to two other functions for Inputting and Displaying the Matrices in Row-Order Format. (In total there will be 8 functions: 6 for the operations and 2 functions for inputting and displaying the data.)

For Addition, Subtraction, Multiplication, and Transpose, it can be 2D array of any size (say Max dimension for both row and Column be 10). So, to prevent users from having to entering 100 (for a 10X10 matrix) elements every time (even for a smaller matrix), you should ask for the number of rows and columns in the matrix before the user would input the values of the matrix elements. Basically, your code should be generic. The point is user should be free to enter 2X3, or 4X2, or 9X9 Matrix. If the operation is not supported (ex. adding two arrays of different dimensions) just print out that the operation is not supported and return to the menu.

For Determinant and Inverse operations, we are giving you the relaxation to choose fixed matrix size of 3X3. (3 rows and 3 column). You do not need to calculate the determinate and inverse operations for any matrix that is not 3x3 (the function can just check to see if the matrix not 3x3. If it is, just print out that the operation is not supported).

Requirements: In the main function you should have a menu in which you will ask the user his or her choice for which of the operations he or she wants to perform. For Ex.

cout

cout

cout

.....

cin>>choice;

After taking the choice value, one should have a switch network to choose which function (for the matrix operation) needs to be called.

I need the inverse function and how to call it in main. It has to work for a 3x3 matrix

Here is the display,input, det function and the main im using

#include iostream #include using namespace std; // input void input (int arr[][10], int row, int col) for (int x e; x row; x++) { for (int y 0; y arr[x][y]; //display matrix void display (int arr][10], int row, int col) cout choice; int r1, c1, r2, c2; int mat1[10][10], mat2[18][10], mat3[10][10]; cout " "; else if (choice 4) cout > rl; cout > cl; if (ri> 10 | c1 > 10) # of columns: "; cout
