S = size(TR)provides size information for a triangulation matrix. The matrix is of sizemtri-by-nv, wheremtriis the number of simplices andnvis the number of vertices per simplex (triangle/tetrahedron, etc). example Examples collapse all ...
A matrix X is invertible if there exists a matrix Y of the same size such that XY=YX=In, where In is the n-by-n identity matrix. The matrix Y is called the inverse of X. A matrix that has no inverse is singular. A square matrix is singular only when its determinant is exactly ...
isscalar(A) 如果size(A)的返回值为[1 1],返回逻辑值1,否则返回逻辑值0 7.ismatrix ismatrix(V) 如果size(V)的返回值[m n]为非负整数(正数和零),返回逻辑值1,否则返回逻辑值0 8.mean M = mean(A) 如果A为向量,返回平均值 如果A为矩阵,计算列的平均值,M为行向量 如果A为多(>2)维矩阵... M...

Full size image A close assessment of the spy plot disclosed a number of other valuable clues. For instance, the only X-ray structure of MMP-11 (i.e., PDB:1HV5) was clearly distinguished from all the others; such a result was in agreement with previous investigation [13] based on rms...
In MATLAB, there is a very useful function called 'reshape', which can reshape a matrix into a new one with different size but keep its original data. You're given a matrix represented by a two-dimensional array, and two positive integers r and c representing the row number and column ...
