Functions and values

Function or value	Description
`merge mapA mapB` Full Usage: `merge mapA mapB` Parameters: mapA : `Map<'key, 'value>` - Frequency map A mapB : `Map<'key, 'value>` - Frequency map B Returns: `Map<'key, 'value>` New frequency map that results from merged maps mapA and mapB.	Merges two maps into a single map. If a key exists in both maps, the value in mapA is superseded by the value in mapB. When applied to continuous data the bandwidths must be equal!This function is not commutative! (merge a b) is not equal to (merge b a) mapA : `Map<'key, 'value>` Frequency map A mapB : `Map<'key, 'value>` Frequency map B Returns: `Map<'key, 'value>` New frequency map that results from merged maps mapA and mapB.
`mergeAdd mapA mapB` Full Usage: `mergeAdd mapA mapB` Parameters: mapA : `Map<'key, ^value>` - Frequency map A mapB : `Map<'key, ^value>` - Frequency map B Returns: `Map<'key, ^value>` New frequency map that results from merged maps mapA and mapB. Values from keys that are present in both maps are handled by f Modifiers: inline Type parameters: 'key, ^value	Merges two maps into a single map. If a key exists in both maps, the value from mapB is added to the value of mapA. When applied to continuous data the bandwidths must be equal!This function is not commutative! (add a b) is not equal to (add b a) mapA : `Map<'key, ^value>` Frequency map A mapB : `Map<'key, ^value>` Frequency map B Returns: `Map<'key, ^value>` New frequency map that results from merged maps mapA and mapB. Values from keys that are present in both maps are handled by f
`mergeBy f mapA mapB` Full Usage: `mergeBy f mapA mapB` Parameters: f : `'value -> 'value -> 'value` - Function to transform values if key is present in both maps. `mapA-value → mapB-value → newValue` mapA : `Map<'key, 'value>` - Frequency map A mapB : `Map<'key, 'value>` - Frequency map B Returns: `Map<'key, 'value>` New frequency map that results from merged maps mapA and mapB. Values from keys that are present in both maps are handled by f	Merges two maps into a single map. If a key exists in both maps, the value is determined by f with the first value being from mapA and the second originating from mapB. When applied to continuous data the bandwidths must be equal!This function is not commutative! (mergeBy f a b) is not equal to (mergeBy f b a) f : `'value -> 'value -> 'value` Function to transform values if key is present in both maps. `mapA-value → mapB-value → newValue` mapA : `Map<'key, 'value>` Frequency map A mapB : `Map<'key, 'value>` Frequency map B Returns: `Map<'key, 'value>` New frequency map that results from merged maps mapA and mapB. Values from keys that are present in both maps are handled by f
`mergeSubtract mapA mapB` Full Usage: `mergeSubtract mapA mapB` Parameters: mapA : `Map<'key, ^value>` - Frequency map A mapB : `Map<'key, ^value>` - Frequency map B Returns: `Map<'key, ^value>` Modifiers: inline Type parameters: 'key, ^value	Merges two maps into a single map. If a key exists in both maps, the value from mapB is subtracted from the value of mapA. When applied to continuous data the bandwidths must be equal!This function is not commutative! (subtract a b) is not equal to (subtract b a) mapA : `Map<'key, ^value>` Frequency map A mapB : `Map<'key, ^value>` Frequency map B Returns: `Map<'key, ^value>`
