MATLAB: Need help in this

Question

can somebody tell me the purpose of this 'sol' sol(1,1)=P; sol(2,1)=X(5);

can you give examples

Answer 1

Apparently sol is an MxN matrix. The code is simply assigning the 1st row, 1st column the value of P. And the second row, first column the value of X(5) -- the fifth element of X.

Without more details, that's all the help I can give.

P = 5;
% create a random vector X so we can select the fifth element
X = randn(100,1);
% create a 2x2 matrix of zeros
sol = zeros(2,2);
% set 1st row, 1st column equal to P
sol(1,1) = P;
%set 2nd row, 1st column equal to the fifth element of X
sol(2,1) = X(5);
