These are the locations in the matrix in which the logical expression is true, in this case, any location greater than 12. Now the expressionA(A > 12) extracts the matrix elements corresponding to the nonzero values of the logical array. The output is always in the form of a column ...

I want to bootstrap this matrix. I have a matrix of indices INDX(nrep,M) with nrep the number of rows which correspond to the number of bootstrap draws, and M the number of of elements in each bootstrap draw. Each element of INDX picks an individual from the original dataset, and ...
elements in it. The other array(2) = [12 11 14 5 1] contains a set of indexes for non-zero elements in array(1) (mapping one-to-one - so 1 should have index 12, 2 - index 11, etc.). How can I sort array(1) with respect to indexes in array(2) with no use of loop ...
working with conditional statements. For example, suppose you want to know if the elements of a matrixAare less than the corresponding elements of another matrixB. The less-than operator returns a logical array whose elements are1where an element inAis smaller than the corresponding element inB...
In this work, a Matrix Based Indexing HDMR method is developed to make the Plain HDMR philosophy employable for the multivariate data partitioning process. This new method will have the ability of dealing with less-variate data sets by partitioning the given data set into univariate, bivariate ...

Hello, I extract the cell subtype using Seurat_4.3.0, and recluster it to analysis. But I have a error: Error in h(simpleError(msg, call)) : error in evaluating the argument 'x' in selecting a method for function 'as.matrix': invalid cha...
When you index a field with IndexOptions.DOCS_AND_FREQS, Lucene will store just the docID and term frequency (how many times that term occurred in that document) for all documents that have a given term. We compute that term frequency by...
logical indexing of a matrix with different columnsDear all, This is my problem: I have a matrix of 3 columns and 100 rows. I want to find for each column the position of cells which contain values <-0.01, cells which contain values >0.01 and the other remaining cells. For each ...
