MATLAB: Is it possible to get index of reshaped matrix

indexing

i have a matrix A of size 1*120 and reshaped it to matrix B of size 10*12….. is it possible to get the index values of where the value of A has gone to B in a matrix C of size 1*120….

The functions ind2sub and sub2ind, give you a more general way of doing it, which expands to more dimensions...

MATLAB: ???index exceeds matrix dimensions

x=1:42
c = 2*x+1

c = zeros(1,42);
for x = 1:42
    a = x;
    b = a + 1;
    c(x) = a + b;
end

x=1:42
c = zeros(size(x));
for i1 = 1:numel(x)
    if x(i1) == i1
        a = x(i1);
        b = a + 1;
    end
    c(i1) = a + b;
end
