How do I form a matrix from an array of rows and columns

A=ones(10)

a=[1 3 5 6 9]

b=[1 2 4 7 9]

A(a,b)=0 should provide A(1,1)=0 A(3,2)=0 A(5,4)=0 A(6,7)=0 A(9,9)=0

Answer 1

[Chunru]

A=ones(10);
a=[1 3 5 6 9];
b=[1 2 4 7 9];
A(sub2ind(size(A), a,b)) = 0;

A

A = 10×10

0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1

 A(a + (b-1)*size(A,1)) = 0

[madhan ravi]

A=ones(10);
a=[1 3 5 6 9];
b=[1 2 4 7 9];
A(a + (b-1)*size(A,1)) = 0

A = 10×10

0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1
