Doubts regarding MATLAB Fundamentals-self paced Course Topic

sir,

In the topic of Matrix Multiplications, regarding Modeling Loons Populations, how the eleements of Population change matrix named as popChange are formed and loons population row matrix elements are also how are they formed. Can you please clarify my doubts.

Hi,

The matrix “popChange” is a 4x4 matrix, created using the matrix notation in MATLAB.The entire matrix is specified within square brackets [ ], and rows are separated by semicolons (;) –

popChange  = [0 0 0 .145; 
             .6 .375 0 0; 
            0 .225 .56 .05; 
             0 0 .35 .86]; 

The array “loons” is a column vector, created using the column vector notation in MATLAB. The elements of the vector are specified within square brackets [ ] and it can be created by taking transpose of a row vector with the help of (‘) notation.

loons = [41 61 52 62]'; 

The elements of the matrix “popChange” and column vector “looms” is sample data .
