How to solve matrix 4x4?
Determinant of 4x4 Matrix. Determinant of a 4×4 matrix is a unique number which is calculated using a particular formula. If a matrix order is n x n, then it is a square matrix. Hence, here 4×4 is a square matrix which has four rows and four columns. If A is square matrix then the determinant of matrix A is represented as |A|.

What is the minor of a 4x4 matrix?
For a 4x4 matrix A, there are 16 different minors. Each minor is the determinant of the matrix obtained from A by removing one row and one column. Specifically, for 1 = < i,j =< 4, the (i,j) minor of A is the determinant of the matrix obtained from A by removing row i and row j.

And this part of the formula.
When can you use cofactor expansion?
Cofactor expansion can be very handy when the matrix has many 0's. Let A=[1a0n−1B] where a is 1×(n−1), B is (n−1)×(n−1), and 0n−1 is an (n−1)-tuple of 0's. Using the formula for expanding along column 1, we obtain just one term since Ai,1=0 for all i≥2. Hence, det(A)=(−1)1+1A1,1det(A(1∣1))=1det(B)=det(B).

Most international development agencies and non-governmental organizations (NGOs) have some experience planning and evaluating projects using the Logical Framework matrix.
What is the Logical Framework?
The Logical Framework is a tool commonly used in international development to plan and evaluate development projects. It is essentially a 4 x 4 matrix [see figure] that was developed for the US Agency for International Development ( USAID) in 1969.
How do managerial traditions inform development projects?
Our point of departure is that performance management tools are not neutral. They are imbued with all sorts of traditions. We examine the traditions implicated in one such management tool, the Logical Framework, by considering its visual design.
So, what are the implications for development projects?
Access to land and food security, for example, implicates all sorts of local and international economic, climatic, cultural, social, and political factors affecting one another.
