deal 

Distribute inputs to outputs

Syntax

• [Y1, Y2, Y3, ...] = deal(X)[Y1, Y2, Y3, ...] = deal(X1, X2, X3, ...)

Description

[Y1, Y2, Y3, ...] = deal(X) copies the single input to all the requested outputs. It is the same as Y1 = X, Y2 = X, Y3 = X, ...

[Y1, Y2, Y3, ...] = deal(X1, X2, X3, ...) is the same as Y1 = X1;
Y2 = X2; Y3 = X3; ...

Remarks

deal is most useful when used with cell arrays and structures via comma-separated list expansion. Here are some useful constructions:

[S.field] = deal(X) sets all the fields with the name field in the structure array S to the valueX. If S doesn't exist, use [S(1:m).field] = deal(X).

[X{:}] = deal(A.field) copies the values of the field with name field to the cell array X. If Xdoesn't exist, use [X{1:m}] = deal(A.field).

[Y1, Y2, Y3, ...] = deal(X{:}) copies the contents of the cell array X to the separate variablesY1, Y2, Y3, ...

[Y1, Y2, Y3, ...] = deal(S.field) copies the contents of the fields with the name field to separate variables Y1, Y2, Y3, ...

Examples

Use deal to copy the contents of a 4-element cell array into four separate output variables.

• C = {rand(3) ones(3,1) eye(3) zeros(3,1)};[a,b,c,d] = deal(C{:})a =    0.9501   0.4860   0.4565    0.2311   0.8913   0.0185    0.6068   0.7621   0.8214b =     1    1    1c =     1   0   0    0   1   0    0   0   1d =     0    0    0

Use deal to obtain the contents of all the name fields in a structure array:

• A.name = 'Pat'; A.number = 176554;A(2).name = 'Tony'; A(2).number = 901325;[name1,name2] = deal(A(:).name)name1 =Patname2 =Tony
