Select a column from a 2D array.
float[][] nums = [[1.0f, 2.0f], [10.0f, 20.0f]]
assert nums.column(0) == [1.0f, 10.0f] as float[]
assert nums.column(1) == [2.0f, 20.0f] as float[]
Process the columns of the array.
double[][] nums = [[1.0f, 2.0f], [10.0f, 20.0f]]
nums.eachColumn {
assert it[0] * 10.0f == it[1]
}
closure - the closure applied on each array columnFlattens a 2D array into a new collection. The items are copied row by row.
Example usage:
float[][] array = [[0.0f, 1.0f], [2.0f, 3.0f]]
assert array.flatten() == [0.0f, 1.0f, 2.0f, 3.0f]
A transpose method for 2D float arrays.
Example usage:
float[][] floats = [[1.0f, 10.0f], [2.0f, 20.0f]]
float[][] expected = [[1.0f, 2.0f], [10.0f, 20.0f]]
def result = floats.transpose()
assert result == expected
assert floats.class.componentType == result.class.componentType
An iterator of the columns of the array.
float[][] nums = [[1.0f, 2.0f], [10.0f, 20.0f]]
assert nums.transpose() == nums.transposing().toList()
