The script below produces good fit:

CreateMDFitWorkspace('ws1','id=x,xmin=0,xmax=10,n=100','x+2*exp(-2*(x-4.6)2)',1) CreateMDFitWorkspace('ws2','id=x,xmin=0,xmax=10,n=100','10-0.5*x+2*exp(-2*(x-4.6)2)',1) GenericFit('ws1',,'composite=CompositeFunctionMD;name=UserFunctionMD,Workspace=ws1,Formula=a+b*x;name=UserFunctionMD,Workspace=ws2,Formula=a+b*x;name=UserFunctionMD,Formula=h*exp(-a*(x-c)2)',Output='res')

Due to wiki formatting in the above test there are some missing symbols:

(1) need to add null string to parameter list as second argument of GenericFit call i.e. GenericFit('ws1','','id=....

(2) need to use ^ symbol in formula for exponentials, e.g. (x-4.6)^2)
