我有一個非常簡單的問題,但我也沒弄明白怎麼解決this.I擁有以下功能定義:將參數傳遞給Matlab的功能
function model = oasis(data, class_labels, parms)
% model = oasis(data, class_labels, parms)
%
% Code version 1.3 May 2011 Fixed random seed setting
% Code version 1.2 May 2011 added call to oasis_m.m
% Code version 1.1 May 2011 handle gaps in class_labels
%
% Input:
% -- data - Nxd sparse matrix (each instance being a ROW)
% -- class_labels - label of each data point (Nx1 integer vector)
% -- parms (do sym, do_psd, aggress etc.)
%
% Output:
% -- model.W - dxd matrix
% -- model.loss_steps - a binary vector: was there an update at
% each iterations
% -- modeo.parms, the actual parameters used in the run (inc. defaults)
%
% Parameters:
% -- aggress: The cutoff point on the size of the correction
% (default 0.1)
% -- rseed: The random seed for data point selection
% (default 1)
% -- do_sym: Whether to symmetrize the matrix every k steps
% (default 0)
% -- do_psd: Whether to PSD the matrix every k steps, including
% symmetrizing them (defalut 0)
% -- do_save: Whether to save the intermediate matrices. Note that
% saving is before symmetrizing and/or PSD in case they exist
% (default 0)
% -- save_path: In case do_save==1 a filename is needed, the
% format is save_path/part_k.mat
% -- num_steps - Number of total steps the algorithm will
% run (default 1M steps)
% -- save_every: Number of steps between each save point
% (default num_steps/10)
% -- sym_every: An integer multiple of "save_every",
% indicates the frequency of symmetrizing in case do_sym=1. The
% end step will also be symmetrized. (default 1)
% -- psd_every: An integer multiple of "save_every",
% indicates the frequency of projecting on PSD cone in case
% do_psd=1. The end step will also be PSD. (default 1)
% -- use_matlab: Use oasis_m.m instead of oasis_c.c
% This is provided in the case of compilation problems.

我想要使用此功能,但我不知道如何設置參數,或使用默認值。在這種情況下,什麼是可變參數,它是一個保持所有其他變量的對象?我可以做一些像語法的東西,我們把參數的名字加上值嗎?例如:
model = oasis(data_example, labels_example, agress = 0.2)
另外,如果我理解正確的,我得到兩個對象的輸出,這是模型和Modeo公司,所以我需要撥打這個電話來接收所有內容,該函數返回?
[model,modeo] = oasis(data_example, labels_example, ?(parms)?)
我解決了用參數創建結構的問題。對於輸出結果,Tamás評論說文本中有一個錯字 – Mike
