(42S) Function Table

[Thomas Klemm]

We can GROW the matrix:

Code:

00 { 45-Byte Prgm }
01▸LBL "FTAB"
02 STO 02
03 R↓
04 STO 01
05 R↓
06 STO 00
07 1
08 2
09 NEWMAT
10 EDIT
11 GROW
12▸LBL 00
13 RCL 00
14 →
15 RCL 00
16 XEQ "FX"
17 →
18 RCL 01
19 STO+ 00
20 DSE 02
21 GTO 00
22 DELR
23 EXITALL
24 END

In addition to that I don't see a reason to use MVAR.

Code:

00 { 10-Byte Prgm }
01▸LBL "FX"
02 X↑2
03 LASTX
04 E↑X
05 ×
06 END

The value of \(x\) can be found in register 00.

Example:

0 ENTER
0.1 ENTER
10
XEQ "FTAB"

x: [ 10×2 Matrix ]

This creates the same matrix as in Eddie's example:

0.0 0.0000
0.1 0.0111
0.2 0.0489
0.3 0.1215
0.4 0.2387
0.5 0.4122
0.6 0.6560
0.7 0.9867
0.8 1.4243
0.9 1.9923
