The document contains two Java programs: one for adding two matrices and another for generating the transpose of a matrix. Each program prompts the user for the dimensions and elements of the matrices, performs the required operation, and displays the result. Input validation is included to ensure the dimensions are positive.

int R, C, i, j ;
