## Loop output as input

(OP)
Hi there

I have written a program that calculates averages of a very large set of data to reduce the amount of data I need to handle. I have attached the algorithm. My problem is that I want to run the algorithm a number of times with different starting values (more than I care to do manually) and get a number of outputs. The new starting values I want to use are output from the previous calculation.

In other words, I want to loop one of the outputs of my algorithm back in as an input and get a table of the results from each calculation.

If you look at the attached mathcad sheet I basically want the computer to automatically do Calc(0) then Calc(b) then Calc(c) x number of times, without having to write out x number of Calc()

Any help would be much appreciated, even if it is to say this is not possible!

### RE: Loop output as input

You can add another function below your Calc function to do this.  For instance:

Results(x):= | table<-Calc(0)
| index<-table[0,2
| for i = 1;x
|      newtable<-Calc(index)
|      table<-augment(table,newtable)
|      index<-newtable[0,2
| table

You could also stack the results instead of augment depending on how you want to display them.
