The .mdx File Format
SIMPLORER 6.0 — Manual 467
The .mdx file is a SIMPLORER intern data format to exchange data between the different programs.
You can create and edit the files with a common Text Editor. The semicolon at the end
of each data set is essential, including the last one.
Data files in .mdx format are structured in a table-like fashion. The data sets are interpreted
as a sequence of k-dimensional value tuples (ai,bi,ci,….) with a record length n (i.e., data field/
table of k columns times n rows). The correlated values of a k-tuple are arranged successively
in the data set:
(a1,b1,…,z1, a2,b2,…,z2, … ,an,bn,…,zn)
\________/ \_______/ … \_______/
1st k-tuple 2nd k-tuple nth k-tuple
In a typical case (time functions, characteristics) the first value in the n-tuple (ai) should represent
the common abscissa (“x”, time “t”…) where the data sets should be in ascending order
of ai ("x", "t", …).
Each file starts with header information for the data sets, which directly follows the “END:=”
statement. All data within a line are separated by a semicolon; a line must be closed by a
semicolon and CR/LF.
