At<T>(int)

Returns a reference to the specified array element. For 2D matrices, i0 is the row index (dimension 0). Do NOT call this with a column index on a row-submatrix obtained from Row(int); use At<T>(int, int) or RowSpan<T>(int) instead. For performance-sensitive pixel loops, prefer AsRows<T>().

public ref T At<T>(int i0) where T : unmanaged

Parameters

i0 int

Index along the dimension 0

T

A reference to the specified array element.

Type Parameters

T
