size(A, 2)表示取矩阵A的列数。如果A是多维矩阵，则表示的仍然是取每个二维矩阵的列数。举例说明如下：如果A是2维矩阵（行向量或列向量可看为行数或列数为1的矩阵）A=[1, 2, 3; 4, 2, 3];col = size(A, 2); % 计算结果为col=3，因为矩阵A的列数为3% 如果A是多维矩阵（以3维...

Takes any number of cell or double arrays and resizes them all to the same dimensions. Also serves to resize any array with removal of extra rows/columns and adding of NaN, 0, or empty string rows/columns. - NotMyMajor/MATLAB_samesize
Create a random matrix and return the number of rows and columns separately. A = rand(4,3); [numRows,numCols] = size(A) numRows = 4 numCols = 3 Input Arguments collapse all A—Input array scalar|vector|matrix|multidimensional array ...

We present a generically applicable approach to determine an extensive set of size-dependent critical quality attributes inside nanoparticulate pharmaceutical products. By coupling asymmetrical-flow field-flow fractionation (AF4) measurements directly in
In this work, we employed MicrobeCensus22 for de novo estimation of the average genome size (AGS) of microorganisms captured in shotgun metagenome sequences (Fig. 1a; Supplementary Data 1). Briefly, MicrobeCensus optimally aligns metagenomic reads to a set of 30 conserved single-copy gene (CSC...

In the first system, three types of polyester with different ductility were used with a constant sand particle size. In the second system, the matrix was the same but sand particle size was changed. Fracture toughness tests were conducted using single-edge notch beam specimen. The fracture ...
