Once you have found the index, you can find the corresponding table x-value from
x
=
dx(index
−
1)
+
x1
If the target x is less than the first x-value in the table, the equation returns zero. If the target x is
greater than on equal to the last x-value in the table, the equation returns an index larger than the table
size. Your program should check for these conditions and handle them appropriately.
[3.3] Delete matrix rows and columns
There is no built-in function to delete a matrix row. This will do it:
mrowdel(m,r)
Func
Return when(r=
1
or r=rowDim(m),subMat(m,mod(r,rowDim(m))+
1
,
1
,rowDim(m)-
1
+mod(r,
rowDim(m))),augment(subMat(m,
1
,
1
,r-
1
); subMat(m,r+
1
,
1
)))
EndFunc
m is the matrix, and r is the number of the row to delete. You will get a Domain error message if r is
less than or equal to zero, or greater than the number of rows of matrix m.
You can also use mrowdel() to delete a column, by finding the transpose, deleting the row, then finding
the transpose again, like this:
(mrowdel(m
,c))
→
n
This deletes column c of matrix m.

[3.4] Reverse list elements
Use this function
listrev(l)
Func
©(list) reverse list elements
seq(l[i],i,dim(l),
1
,
⁻1
)
EndFunc
to reverse the elements of list l. For example, listrev({1,2,3,4,5}) returns {5,4,3,2,1}

[3.5] Unexpected NewMat() operation in Cylindrical and Spherical vector modes
If you use NewMat(1,2) to make a new matrix in the Rectangular vector format mode, you get [[0,0]] as
expected. But if the vector format mode is set to Cylindrical or Spherical, you'll get
[[0,
