Mathematica Matrix creation help


Hi,

I have a whole bunch of data (Arrays of the form H1, H2, H3 etc) that I want to crunch to create 10 more variables. I did:


For[i=1,i<23,i++,{f1(i),f2(i),..,f10(i)}>>>"temp.mx"]

Where fj(i)= fj(H1[[i]],H2[[i]],...), the functions are different functions of the numerical data I have.

Now when I try to Import "temp.mx" I get all kinds of things except a 22x10 matrix that I really badly want.

data5=Import["temp.mx","Table"]
Dimensions[data5]

This gives the result that data is 110 dimensions where each of my 10 data for each "i" is stored as 5 separate pieces of data, giving data5 a dimenion of 5*22=110

When I do


data5=Import["temp.mx"]
Dimensions[data5]


This time I get Dimension {} and all data is stored as one piece.

How can I store my calculations such that the result is a 22x10 matrix from which data can be easily extracted? This situation is driving me insane. Any help will be greatly appreciated.

Thanks

Hi,

I understand this compulsion to use For[] cannot be resisted.
The result is often problems like what you are seeing.

Try
Table[{f1[i],f2[i],..,f10[i]},{i,1,22}]>>"temp.mx"
