eigen3 - Convert to inHomogeneous cordinates Eigen::MatrixXf -


i have 3x1000 matrix eigen::matrixxf. need divide matrix 3rd row.

a(0,:) = a(0,:) / a(2,:) a(1,:) = a(1,:) / a(2,:) a(2,:) = a(2,:) / a(2,:)

how can perform operation in eigen. in particular cannot find componentwise division

use array:

a.array() /= a.array().col(2);

for more information, see documentation.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
