Q20. Double for loop - If/else on matrices A large matrix of random numbers from 0 to 9 will be generated in variable P like shown below: $P = egin{bmatrix} x_{1,1} & \dots & x_{1,n} \\ \vdots & \ddots & \vdots \\ x_{m,1} & \dots & x_{m,n} \end{bmatrix}$ Use a double for loop to cycle through all the elements of P.

          Q20. Double for loop - If/else on matrices
A large matrix of random numbers from 0 to 9 will be generated in variable P like shown below:
$P = egin{bmatrix} x_{1,1} & \dots & x_{1,n} \\ \vdots & \ddots & \vdots \\ x_{m,1} & \dots & x_{m,n} \end{bmatrix}$
Use a double for loop to cycle through all the elements of P. In a variable S, store one of the following results based on the corresponding element in P:
\begin{itemize}
    \item If $P_{rc} < 3$ then $S_{rc} = -1$
    \item If $3 \le P_{rc} < 7$ then $S_{rc} = 0$
    \item If $P_{rc} \ge 7$ then $S_{rc} = 1$
\end{itemize}

Q20. Double for loop - If/else on matrices
A large matrix of random numbers from 0 to 9 will be generated in variable P like shown below:
P = eginbmatrix x1,1 … x1,n
⋮ ⋱ ⋮
xm,1 … xm,n
Use a double for loop to cycle through all the elements of P. In a variable S, store one of the following results based on the corresponding element in P:

* If Prc < 3 then Src = -1

* If 3 ≤ Prc < 7 then Src = 0

* If Prc≥ 7 then Src = 1

Script
1 % Matrix of random numbers P
2 P = randi([0 9], randi([400 600]), randi([400 600]));
3 % Write a double for loop to check elements of P and store results in S
