The video illustrates how to modify the elements of a matrix to either 1 or 0 using specific code. The method transforms all positive values in the matrix to 1, while all negative or zero values are converted to 0. The operation is demonstrated with an example using pre-defined matrix ‘A.’ The necessary code is run step by step: “A = A.*(A>0)” converts all negative or zero values into zero, and then “A = A./(A + 1.*(A==0))” transforms remaining positive values into 1.
