"build a matrix" is a correct and usable phrase in written English.
It refers to the process of constructing or creating a matrix, which is a rectangular array of numbers or symbols. You can use this phrase when explaining a step-by-step process or procedure for creating a matrix, such as in a math or computer science lesson. For example: "To solve this system of linear equations, we first need to build a matrix by arranging the coefficients and constants into rows and columns."
It will force the state to re-engage with the economy and to build a matrix of institutions that will support innovation and investment, rather as it did between 1931 and 1950.
The informative data deriving from the literature spectra were combined with the stochastic component extracted from a sample spectrum recorded with a prototype instrument, allowing us to build a matrix containing thousands of simulated spectra of gaseous mixtures, accounting for the presence of different components at different concentrations.
During this step the technological projections will be summarized to build a matrix, which will later be used to construct raw pathways.
Given that the dataset contains more than one million customers and almost 350k items, to build a matrix 'customers × items' would generate a ∼370 billion cells matrix, that is redundant for our purposes.
In order to compute the ZF equalizer applied at the receiver on the received samples, the most practical method is probably to build a matrix model of the convolution with the MIMO channel and to compute the corresponding matrix equalizer [20].
As each pair of indexes (i, j) has a single value of c i, j, we can build a matrix C whose row index is the sector number, i, and whose column index is the number of cell, j, within that sector (see Figure 2).
You built a matrix of hundreds of cast-off laptops to bring attention to electronic waste.
First, we built a matrix which includes pairwise correlation coefficients between all pairs of genes [ 39].
DiffBind builds a matrix with the consensus peaks, which have been obtained with a "minimum overlap" of 3, considering the replicates number for each condition.
We downloaded their data from http://acgt.cs.tau.ac.il/prima/PRIMA.htm and built a matrix of 15,476 rows (representing genes) by 432 columns (representing TF binding site motifs), where each entry in the matrix contains the number of times each motif was found in the upstream region of the gene (Additional File 6).
