min_axis_f32

void min_axis_f32(const float * in, float * out, int outer, int reduce_dim, int inner)

Reduces a single axis by elementwise minimum into a packed (outer, inner) output.

Identity element is +inf; an empty reduce dimension yields +inf per output cell. Uses the generic axis_reduce template.
