Flat
Flat
Allows addressing a matrix element through one index instead of two.
bool matrix::Flat(
const ulong index, // index
const double value // value to set
);
double matrix::Flat(
const ulong index, // index
);Parameters
- index
[in] Flat index
- value
[in] Value to set by given index.
Return Value
Value by given index.
Note
For the matrix mat(3,3), access can be written as follows:
- reading: ‘x=mat.Flat(4)’, which is equivalent to ‘x=mat[1][1]’
- writing: ‘mat.Flat(5, 42)’, equivalent to ‘mat[1][2]=42’
Example
matrix matrix_a={{10,3,2},{1,8,12},{6,5,4},{7,11,9}};
Print("matrix_a\n",matrix_a);
ulong arg_max=matrix_a.ArgMax();
Print("max_value=",matrix_a.Flat(arg_max));
matrix_a.Flat(arg_max,0);
arg_max=matrix_a.ArgMax();
Print("max_value=",matrix_a.Flat(arg_max));
/*
matrix_a
[[10,3,2]
[1,8,12]
[6,5,4]
[7,11,9]]
max_value=12.0
max_value=11.0
