How can I stop my program and ask for the wish operation?

1 view (last 30 days)
Hello everyone, I have this program who ask for rows of matrix and columns. My problem is that once I have already asked for columns and rows of matrix A and B I need to ask what operation the person wants to do. For example. I need to ask "Selesct pointwise operation of matrices A and B: 1: Multiplication 2:Division 3:Exponential.
However my program realize the mutiplication and division by itself and I need to stop it and ask first.
disp(' ');
switch_1=1;
while switch_1==1
rows_matrix_A=input('Enter the rows of Matrix A => ');
columns_matrix_A=input('Enter the columns of Matrix A => ');
rows_matrix_B=input('Enter the rows of Matrix B => ');
columns_matrix_B=input('Enter the columns of Matrix B => ');
disp(' ')
if columns_matrix_A==rows_matrix_B
for i=1:rows_matrix_A
for j=1:columns_matrix_A
A(i,j)=input('Enter element of matrix A => ');
end
end
disp(' ')
for i=1:rows_matrix_B
for j=1:columns_matrix_B
B(i,j)=input('Enter element of matrix B => ');
end
end
disp(' ')
disp('Matrix A: ')
disp(A)
disp(' ')
disp('Matrix B: ')
disp(B)
C=A*B;
disp(' ')
disp('Matrix C: ')
disp(C)
D=A/B;
disp(' ')
disp('Matrix C: ')
disp(D)
else
disp('Error, Standard multiplication cannot be perfomed! ')
disp(' ')
end
switch_1=input('DO you want to run the program again? 1=YES 2=NO ');
disp(' ')
end

You can use a if
umi = '1 = A*B 2 = A/B ';
opc = input(umi); %input (multiply or divide?)
disp(' ')
disp('Matrix A: ')
disp(A)
disp(' ')
disp('Matrix B: ')
disp(B)
if (opc == 1)
C=A.*B;
disp(' ')
disp('Matrix C: ')
disp(C)
elseif (opc == 2)
D=A./B;
disp(' ')
disp('Matrix C: ')
disp(D)
end
