Oct2Py.feval
|
Run a function in Octave and return the result.
Parameters
----------
func_path: str
Name of function to run or a path to an m-file.
func_args: object, optional
Args to send to the function.
nout: int, optional
Desired number of return arguments, defaults to 1.
store_as: str, optional
If given, saves the result to the given Octave variable name
instead of returning it.
verbose : bool, optional
Log Octave output at INFO level. If False, log at DEBUG level.
stream_handler: callable, optional
A function that is called for each line of output from the
evaluation.
timeout: float, optional
The timeout in seconds for the call.
plot_dir: str, optional
If specificed, save the session's plot figures to the plot
directory instead of displaying the plot window.
plot_name : str, optional
Saved plots will start with `plot_name` and
end with "_%%.xxx' where %% is the plot number and
xxx is the `plot_format`.
plot_format: str, optional
The format in which to save the plot.
plot_width: int, optional
The plot with in pixels.
plot_height: int, optional
The plot height in pixels.
Notes
-----
The function arguments passed follow Octave calling convention, not
Python. That is, all values must be passed as a comma separated list,
not using `x=foo` assignment.
Examples
--------
>>> from oct2py import octave
>>> cell = octave.feval('cell', 10, 10, 10)
>>> cell.shape
(10, 10, 10)
>>> from oct2py import octave
>>> x = octave.feval('linspace', 0, octave.pi() / 2)
>>> x.shape
(1, 100)
>>> from oct2py import octave
>>> x = octave.feval('svd', octave.hilb(3))
>>> x
array([[ 1.40831893],
[ 0.12232707],
[ 0.00268734]])
>>> # specify three return values
>>> (u, v, d) = octave.feval('svd', octave.hilb(3), nout=3)
>>> u.shape

-------
The Python value(s) returned by the Octave function call.

Oct2Py.eval
|
Evaluate an Octave command or commands.
Parameters
----------
cmds : str or list
Commands(s) to pass to Octave.
verbose : bool, optional
Log Octave output at INFO level. If False, log at DEBUG level.
stream_handler: callable, optional
A function that is called for each line of output from the
evaluation.
timeout : float, optional
Time to wait for response from Octave (per line). If not given,
the instance `timeout` is used.
nout : int, optional.
The desired number of returned values, defaults to 0. If nout
is 0, the `ans` will be returned as the return value.
temp_dir: str, optional
If specified, the session's MAT files will be created in the
directory, otherwise a the instance `temp_dir` is used.
a shared memory (tmpfs) path.
plot_dir: str, optional
If specificed, save the session's plot figures to the plot
directory instead of displaying the plot window.
plot_name : str, optional
Saved plots will start with `plot_name` and
end with "_%%.xxx' where %% is the plot number and
xxx is the `plot_format`.
plot_format: str, optional
The format in which to save the plot (PNG by default).
plot_width: int, optional
The plot with in pixels.
plot_height: int, optional
The plot height in pixels.
plot_res: int, optional
The plot resolution in pixels per inch.
**kwargs Deprectated kwargs.
Examples
--------
>>> from oct2py import octave
>>> octave.eval('disp("hello")') # doctest: +SKIP
hello
>>> x = octave.eval('round(quad(@sin, 0, pi/2));')
>>> x
1.0
>>> a = octave.eval('disp("hello");1;') # doctest: +SKIP
hello
>>> a = octave.eval('disp("hello");1;', verbose=False)
>>> a
1.0
>>> from oct2py import octave
>>> lines = []
>>> octave.eval('for i = 1:3; disp(i);end', \
stream_handler=lines.append)
>>> lines # doctest: +SKIP
[' 1', ' 2', ' 3']
Returns
-------
out : object
Octave "ans" variable, or None.
Notes
-----
The deprecated `log` kwarg will temporarily set the `logger` level to
`WARN`. Using the `logger` settings directly is preferred.
The deprecated `return_both` kwarg will still work, but the preferred
method is to use the `stream_handler`. If `stream_handler` is given,
the `return_both` kwarg will be honored but will give an empty string
as the reponse.
Raises
------
Oct2PyError
If the command(s) fail.
