What is the order of largest square Submatrix?

The largest square submatrix is formed by cells (0, 2) , (3, 2) , (0, 5) , and (3, 5) . The brute-force solution is to consider every square submatrix and check if it is surrounded by all 1’s .

How do you find a rectangle in a matrix?

Find Rectangle in binary matrix

  1. Input Format. The first argument given is the integer matrix A.
  2. Output Format. Return 1 if there exists such rectangle/square whose all four corners are 1 else return 0.
  3. Constraints 1 <= N, M <= 200 0 <= A[i] <= 1.
  4. For Example Input 1: A = [ [0, 1, 1] [0, 1, 1] [0, 1, 0] ] Output 1: 1.

Size of a matrix = number of rows × number of columns.

Which matrix contains all the entries as only 0’s and 1’s?

Specific patterns for entries

Name Explanation
Hollow matrix A square matrix whose main diagonal comprises only zero elements.
Integer matrix A matrix whose entries are all integers.
Logical matrix A matrix with all entries either 0 or 1.

What is square submatrix of a matrix?

A sub-matrix is a matrix obtained from the given matrix by deletion of several (possibly, zero or all) rows/columns from the beginning and several (possibly, zero or all) rows/columns from the end. A square matrix is a matrix which has the same number of rows and columns.

How do you find the size of the resulting matrix?

You take the number of rows from the first matrix (2) to find the first dimension, and the number of columns from the second matrix (2) to find the second dimension. Another way to think of this: The dimensions of their product is the two outside dimensions.

What do you mean by sub matrix?

Submatrix meaning Filters. (mathematics) A matrix formed by selecting certain rows and columns from a larger matrix.

What is sub matrix example?

is a submatrix of A formed by rows 1,2 and columns 1,3,4. This submatrix can also be denoted by A(3;2) which means that it is formed by deleting row 3 and column 2.
