Specify Global Cell Arrays at the Command Line - MATLAB & Simulink (original) (raw)

To specify global cell array inputs, use the -globals option of the codegen command with this syntax:

codegen myfunction -globals {global_var, {type_object, initial_value}}

For example:

To specify that the global variable g is a 1x3 cell array whose elements have class double and whose initial value is {1 2 3}, use:
codegen myfunction -globals {'g', {coder.typeof({1 1 1}), {1 2 3}}}
Alternatively, use:
t = coder.typeof({1 1 1});
codegen myfunction -globals {'g', {t, {1 2 3}}}
The global variable g is a 1x3 homogeneous cell array whose elements are 1x1 double.
To make g heterogeneous, use:
t = makeHeterogeneous(coder.typeof({1 1 1}));
codegen myfunction -globals {'g', {t, {1 2 3}}}
To specify that g is a cell array whose first element has type char, whose second element has type double, and whose initial value is {'a', 1}, use:
codegen myfunction -globals {'g', {coder.typeof({'a', 1}), {'a', 1}}}
The global variable g is a 1x2 heterogeneous cell array whose first element is 1x1 char and whose second element is 1x1 double.
To specify that g is a cell array whose first element has type double, whose second element is a 1x2 double array, and whose initial value is{1 [2 3]}, use:
codegen myfunction -globals {'g',{coder.typeof({1 [2 3]}),{1 [2 3]}}}
Alternatively, use:
t = coder.typeof({1 [2 3]});
codegen myfunction -globals {'g', {t, {1 [2 3]}}}
The global variable g is a 1x2 heterogeneous cell array whose first element is 1x1 double and whose second element is 1x2 double.

Global variables that are cell arrays cannot have variable size.
