How to write the matrix with blank element? - MATLAB.
If A is a nonempty matrix, all(A) treats the columns of A as vectors, returning a row vector of logical 1's and 0's. If A is an empty 0-by-0 matrix, all(A) returns logical 1 (true). If A is a multidimensional array, all(A) acts along the first non-singleton dimension and returns an array of logical values.

You can write any system of equations as a matrix. Take a look at the following system: To express this system in matrix form, you follow three simple steps: Write all the coefficients in one matrix first. This is called a coefficient matrix. Multiply this matrix with the variables of the system set up in another matrix. This is sometimes called the variable matrix. Insert the answers on the.
