Detailed Description

Matlab wrapper for DS mapping functions step() to a matlab function.

The identifier of matlab function is stored in attribute name. This identifier defines:

• function to call to do a step(): name_step.m
• workspace variable to write input to: name_input

void bdm::mexDS::from_setting

(

const Setting &

set

)

[inline, virtual]

Create memory data source from mxArray.

        system={
                type="mexDS";
                step_name="";              // name of function to call
                input_name="";             // name of workspace variable where inputs are written
                rv_out = {class='RV',...}  // identification of outputs
                rv_in = {class='RV',...}   // identification of inputs
                };

MemDS with the above fields will be created;

Reimplemented from bdm::root.
