Print matrix in diagonal pattern Easy Accuracy: 43.66% Submissions: 1938 Points: 2 . Algorithm to print a matrix diagonally Let A be a matrix of dimension M x N. Minor diagonal of a matrix, divides it into two sections. As observed the row index increases by 1 and the column index decreases by 1 as you move down the diagonal. Multiplication of both Matrix is: 38 34 19 89 88 49 132 146 81. This article is contributed by Sahil Chhabra. Print lower triangular matrix pattern from given array in C Program. For example matrix of size 3 x 4 should display like this: Source Code The task is to print the matrix of n x n of the diagonal pattern. For first or last row. An R*C matrix is passed as the input to the program. How can I fill it with random numbers and then I need to show main diagonal and another diagonal over and below matrix. If n is 3 then to print a matrix in Diagonal pattern is − So the output will be like − Example Input: 3 Output: 1 2 4 3 5 7 6 8 9 Input: 4 Output: 1 2 4 7 3 5 8 11 6 9 12 14 10 13 15 16 The program must print the values in zig-zag order diagonally. This is how matrices are represented in C. i and j – are loop variables of two different for loops where i points to the rows and j points to the columns of our matrix. Program to print a matrix in Diagonal Pattern. row index increases by 1 and column index decreases by 1 as you move down the diagonal.

I thought about cycle but I don't know how to use it. For each row stars are printed in four conditions. If all elements in lower-section consists of zeros, it is a upper-triangular matrix and If all elements in upper-block consists of zeros, it is a lower-triangular matrix. For example, in the below matrix, the elements should be printed in the marked (in red) order, and the final output should be as shown below: Solution: We did a similar question yesterday, that was to print two diagonals of the matrix. The above pattern is a simple hollow square star pattern if we remove diagonal. Create a matrix of size N X N which will store the pattern before printing.
