MATLAB: Is CPLEX an open-source optimization toolbox

cplex

I am using intlinprog solver for my problem as an integer linear programming. For the problem I am working on, I found most of the literature reviews use CPLEX instead. I am new in optimization and CPLEX, my question is: is CPLEX an open source toolbox? is it free license so that one can download it and use it? Thanks

No, it's commercial.

MATLAB: FastText word embedding support package

To answer my own question, the following example code shows how to add words to the embedding vocabulary. This requires a new embedding object to be created.

>> emb = fastTextWordEmbedding; 
>> vocab = emb.Vocabulary; 
>> mat = word2vec(emb, vocab);
>> newvocab = [vocab "New Word 1" "New Word 2"]; 
>> newmat = [mat; randn(2,300)]; 
>> newemb = wordEmbedding(newvocab, newmat);

In addition, I have confirmed it is possible to use the fastText pretrained 2 Million words (600 billion tokens) rather than the default 1 Million words (16 billion token) which is provided with the MATLAB fastTextWordEmbedding function.

To do this, replace the "wiki-news-300d-1M.vec.zip" file with the alternative pre-trained word vectors file from https://fasttext.cc/docs/en/english-vectors.html

MATLAB: Call cplex from matlab

add the path who you are installed cplex

>> addpath ('C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic123\cplex\matlab\x64_win64')

and save the path

>>savepath

and same way for running the examples

>>addpath ('C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic123\cplex\examples\src\matlab')
>>savepath
