Return values of Map object

Syntax

Description

Note

dictionary is recommended overcontainers.Map because it accepts more data types as keys and values and provides better performance. (since R2022b)

valueSet = values([M](#d126e1973752)) returns all the values of the input Map object as a cell array.

example

valueSet = values([M](#d126e1973752),[keySet](#d126e1973777)) returns the values that correspond to the keys specified in the cell arraykeySet. The output argument valueSet has the same size as keySet.

Examples

collapse all

Create a Map object.

ids = [437 1089 2362]; names = {'Li, N.','Jones, R.','Sanchez, C.'}; M = containers.Map(ids,names)

M = Map with properties:

    Count: 3
  KeyType: double
ValueType: char

Return a cell array containing its values.

valueSet = 1×3 cell {'Li, N.'} {'Jones, R.'} {'Sanchez, C.'}

Create a Map object.

months = {'Jan','Feb','Mar','Apr'}; rainfall = [327.2 368.2 197.6 178.4]; M = containers.Map(months,rainfall)

M = Map with properties:

    Count: 4
  KeyType: char
ValueType: double

Return values that correspond to specified keys.

keySet = {'Jan','Feb'}; valueSet = values(M,keySet)

valueSet=1×2 cell array {[327.2000]} {[368.2000]}

Return one value. Even when you specify one key, you must specify it as a cell array.

keySet = {'Apr'}; valueSet = values(M,keySet)

valueSet = 1×1 cell array {[178.4000]}

Input Arguments

collapse all

Keys corresponding to values to return from the Map object, specified as a cell array.

Even when you specify keys as strings, the keys must be contained in a cell array.
