Question

Construct a 4x3 matrix with rank l?

Answer 1

To construct a 4x3 matrix with rank l, we need to ensure the number of linearly independent rows or columns is equal to l. An example is provided assuming l equals 2.

Step-by-step explanation:

A 4x3 matrix refers to a matrix with 4 rows and 3 columns. To construct a matrix with rank l, we need to make sure that the number of linearly independent rows or columns in the matrix is equal to l. Since l is not mentioned in the question, we cannot determine the specific values of the matrix. However, to demonstrate how to construct such a matrix, let's assume l equals 2, meaning we need a 2x2 submatrix with a nonzero determinant.

Here's an example:

1 0 0
0 1 0
0 0 0
0 0 0
