 In order for schedule code generator to generate the code, other than specify the schedule for the useEquation, a schedule has to be specified for each special statement of each input/ouput of the useEquation.
+The following command set the SpaceTimeMap for the (n)th input/output of a useEuqation identified with lable:
+<sxh cs; gutter:false>
+setSpaceTimeMapForUseEquationOptimization(program, system, label, isInput, n, SpaceTimeMapForMalloc, SpaceTimeMapForValueCopy, SpaceTimeMapForMemoryFree);
+</sxh>
+The parameter isInput sepcifies whether the SpaceTimeMap is specified for input or not, and the last three prarameter specifies the space time map for the three special statement attached to the current input/output. Those specification can also be specified separately with the following command:
+<sxh cs; gutter:false>
+setSpaceTimeMapForMemoryAllocation(program, system, label, isInput, n, SpaceTimeMap);
+setSpaceTimeMapForValueCopy(program, system, label, isInput, n, SpaceTimeMap);
+setSpaceTimeMapForMemoryFree(program, system, label, isInput, n, SpaceTimeMap);
+</sxh>
+The following script consists all the commands that specifies the TargetMapping for the matrix multiplication example and generates the code.
+<sxh cs; gutter:false>
