-======Schedule Code Generator for SubSystem====== 
-Given an affine system with subsystems/useEquations, this page shows how to specify the targetmapping for the system and generate the code.  
-====Example program with subsystem==== 
- 
-The following code is the alpha program for matrix matrix multiplication with dot-product subsystem.  
-<sxh alphabets; gutter:false> 
-affine matrix_product_SubSyst {N,K,M | N>0 && K>0 && M > 0} // Product between a N*K matrix and a K*M matrix 
-input 
- float A {i,k | 0<=i<N && 0<=k<K}; 
- float B {k,j | 0<=k<K && 0<=j<M}; 
-output 
- float C {i,j | 0<=i<N && 0<=j<M}; 
-let 
- use {iP,jP|0<=iP<N && 0<=jP<M} dot_product[K] ((pi,pj,k->pi,k)@A,(pi,pj,k->k,pj)@B) returns (C); 
-. 
- 
-affine dot_product {N| N>0} // Product between 2 vector of size N 
-input 
- float vect1 {i | 0<=i<N }; 
- float vect2 {i | 0<=i<N }; 
-output 
- float Res; 
-local 
- float temp {i | 0<=i<N}; 
-let 
- temp[i] = case 
- {i|i==0}   : vect1[0] * vect2[0]; 
- {i |0<i<N} : temp[i-1] + vect1[i]*vect2[i];  
- esac; 
- Res[] = temp[N-1]; 
-.

-</sxh>

-The program contains two systems. The dot_product system takes two vectors as inputs and computes the doc product of these two vectors. The matrix_product_SubSyst computes matrix C=A*B, the (ip,jp)th element for the answer matrix C is computed by calling the dot product subsystem, and the (ip)th row of A, and (jp)th column of B is passed as input to the subsystem call.
