Syntax

valueSet = values(M)
valueSet = values(M,keySet)

Description

Note

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

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

example

valueSet = values(M,keySet) returns the values that correspond to the keys specified in the cell array keySet. The output argument valueSet has the same size as keySet.

Open Live Script

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 = values(M)
valueSet = 1×3 cell
    {'Li, N.'}    {'Jones, R.'}    {'Sanchez, C.'}
Open Live Script

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
