functions in std.i  m
mac_primitives

mac_primitives, file
sets FILE primitive data types to be native to MacIntosh, 8 byte double.
interpreted function, defined at i0/std.i line 2011

macl_primitives

macl_primitives, file
sets FILE primitive data types to be native to MacIntosh, long double.
interpreted function, defined at i0/std.i line 2019

max

max(x)
or max(x, y, z, ...)
returns the scalar maximum value of its array argument, or, if
more than one argument is supplied, returns an array of the
maximum value for each array element among the several arguments.
In the multiargument case, the arguments must be conformable.
builtin function, documented at i0/std.i line 720

min,
sum,
avg

median

median(x)
or median(x, which)
returns the median of the array X. The search for the median takes
place along the dimension of X specified by WHICH. WHICH defaults
to 1, meaning the first index of X. The median function returns an
array with one fewer dimension than its argument X (the WHICH
dimension of X is missing in the result), in exact analogy with
rank reducing index range functions. If dimsof(X)(WHICH) is
odd, the result will have the same data type as X; if even, the
result will be a float or a double, since the median is defined
as the arithmetic mean between the two central values in that
case.
interpreted function, defined at i0/std.i line 1021

sort

merge

merge(true_expr, false_expr, condition)
returns the values TRUE_EXPR or FALSE_EXPR where CONDITION is
nonzero or zero, respectively. The result has the data type of
TRUE_EXPR or FALSE_EXPR, promoted to the higher arithmetic type
if necessary. The result has the dimensions of CONDITION.
The number of elements in TRUE_EXPR must match the number of
nonzero elements of CONDITION, and the number of elements in
FALSE_EXPR must match the number of zero elements of CONDITION.
(TRUE_EXPR or FALSE_EXPR should be nil if there are no such
elements of CONDITION. Normally, TRUE_EXPR and FALSE_EXPR should
be 1D arrays if they are not nil.)
This function is intended for vectorizing a function whose
domain is divided into two or more parts, as in:
func f(x) {
big= (x>=threshhold);
wb= where(big);
ws= where(!big);
if (is_array(wb)) {
xx= x(wb);
fb=
}
if (is_array(ws)) {
xx= x(ws);
fs=
}
return merge(fb, fs, big);
}

merge2

merge2(true_expr, false_expr, condition)
returns the values TRUE_EXPR or FALSE_EXPR where CONDITION is
nonzero or zero, respectively. The result has the data type of
TRUE_EXPR or FALSE_EXPR, promoted to the higher arithmetic type
if necessary. Unlike the merge function, TRUE_EXPR and FALSE_EXPR
must be conformable with each other, and with the CONDITION.
interpreted function, defined at i0/std.i line 833

merge2,

min

min(x)
or min(x, y, z, ...)
returns the scalar minimum value of its array argument, or, if
more than one argument is supplied, returns an array of the
minimum value for each array element among the several arguments.
In the multiargument case, the arguments must be conformable.
builtin function, documented at i0/std.i line 710

mkdir

mkdir, directory_name
rmdir, directory_name
Create DIRECTORY_NAME with mkdir, or remove it with rmdir.
The rmdir function only works if the directory is empty.
builtin function, documented at i0/std.i line 1571

cd,
lsdir,
get_cwd,
get_home
