% V contains NaNs which are not used to display, however it makes GLTF choke. We need to remove any vertex that has even a single NaN. So first make an array where each element corresponds to a vertex, and is true only if all coordinates of that vertex are non-NaNs. temp1=all(~i...

小提示:在MATLAB的内部资料结构中,每一个矩阵都是一个以行为主(Column-oriented )的阵列(Array)因此对於矩阵元素的存取,我们可用一维或二维的索引(Index)来定 址。举例来说,在上述矩阵A中,位於第二列、第三行的元素可写为A(2,3)(二维索引)或

The column permutation E is chosen so that abs(diag(R)) is decreasing. [Q,R] = QR(A,0) produces the economy size decomposition. If A is m-by-n with m n, then only the first n columns of Q are computed. 4. 特征值与特征矢量 (Eigenvalues and eigenvectors). MATLAB 中使用函数 eig...
Then, you are changing the element in the second row, first column to have the value of 37. Then, you are printing arr_3 to verify that the specified change has been made. Finally, you are printing arr_2 to verify that no changes have occurred in arr_2, as expected....
