Question

How to calculate the normal and trace of square matrix in TypeScript

Answer 1

function CalculateNormal(matrix: number[][]) {
    let normal: number = 0;
 
    for (let i: number = 0; i < matrix.length; i++) {
        for (let j: number = 0; j < matrix.length; j++) {
            normal += matrix[i][j] * matrix[i][j];
        }
    }
 
    return Math.sqrt(normal);
}
 
function CalculateTrace(matrix: number[][]) {
    let trace: number = 0;
 
    for (let: number i = 0; i < matrix.length; i++) {
        trace += matrix[i][i];
    }
 
    return trace;
}
 
const matrix: number[][] = [[1, 1, 1, 1, 1],
                            [2, 2, 2, 2, 2],
                            [3, 3, 3, 3, 3],
                            [4, 4, 4, 4, 4],
                            [5, 5, 5, 5, 5]];
 
console.log(CalculateTrace(matrix));
 
console.log(CalculateNormal(matrix));
