cofactor function

Compute cofactor of a matrix based on row r and column c.

cofactor(x, r, c)

Arguments

• x: matrix whose cofactor is desired to be computed
• r: row number
• c: column number

Returns

cofactor of x, w.r.t. row r and column c.

Note

needs the function `minor'' in memory. attaches sign (-1)^(r+c) to the minor.

Examples

## The function is currently defined as
function (x, r, c) 
{
    out = minor(x, r, c) * ((-1)^(r + c))
    return(out)
  }
