IntroductionIn this post, I am going to write a c program to find the inverse of the 2Γ2 matrix. For this, we will use a two-dimensional Read Switch Case in C Program to Calculate Area of Circle and TriangleThis program will work only for the 2Γ2 matrix. For writing this program, we must know to find the inverse of the matrix. Basically, this is the topic of mathematics. Before writing this program, let me tell you the steps for finding the the 2Γ2 matrix from the the determinant of this matrix. If the determinant is 0 then terminate the program and read another matrix. We are going to divide the adjoint of matrix with this value of determinant. We know that we can divide anything by find the adjoint of the we will get our final output. Divide the adjoint of matrix by determinant of the same matrix and this is the worry I am going to explain the above steps and after that, you can see the actual c program. Letβs see the above steps in Read C Program to Print Multiples of 5 using do-while loop1. Read the 2Γ2 matrix from the that matrix is and we are calling it as matrix Calculate the determinant of this this step, we are going to find the determinant of the matrix A .As you can see from the above figure, the determinant of the matrix is not equal to 0. Now, we can go to the next Find the adjoint of the the given matrix A, for finding the adjoint of the matrix, interchange the position of 1 and 4 and change the sign of 2 and 3. So the adjoint of the matrix will look like4. Divide the adjoint of matrix by the determinantFormula Used A-1=Adjoint of A / Determinant of AHere, A-1 is nothing but the inverse of matrix hope you have understood all the steps. Now, you can easily write a c program to find the inverse of the 2Γ2 matrix. But if you have any problems, then see the following program.include include int main { int A[2][2],d,adjA[2][2]; int i,j; float invA[2][2]; printf"Enter elements for 2 * 2 matrix\n"; fori=0;i<2;i++ { forj=0;j<2;j++ { //Reading Matrix A scanf"%d",&A[i][j]; } } /* Calculate determinant of matrix A */ d = A[0][0]*A[1][1]-A[0][1]*A[1][0]; ifd==0 { printf"Determinant cannot be ZERO"; return 0; } /* Find adjoint of matrix A */ adjA[0][0]=A[1][1]; adjA[1][1]=A[0][0]; adjA[0][1]=-A[0][1]; adjA[1][0]=-A[1][0]; printf"Matrix A is\n"; fori=0;i<2;i++ { forj=0;j<2;j++ { printf"%d ",A[i][j]; } printf"\n"; } /* Find Inverse of A */ printf"Inverse of Matrix A is\n"; fori=0;i<2;i++ { forj=0;j<2;j++ { invA[i][j]=adjA[i][j]/floatd; printf"%.1f ",invA[i][j]; } printf"\n"; } return 0; } Output 1Output 2I hope, you have understood this program.
