Dear you,

this is LearningYard Academy!

Today,the editor brings you Matlab intensive reading reproduction paper.

Welcome your visit!

The reading time of this tweet is about 5 minutes, please read it with patience.

本周小编将从思维导图、精读内容、知识补充三个板块介绍如何计算除了对角线的倒数的和。

This week, I will introduce how to calculate the sum of the inverse of in addition to the diagonal in three sections: mind map, intensive reading content, and knowledge supplement.

01思维导图

02精读内容

上周我们计算出了的倒数，本周进行下一步操作，计算-除了对角线的倒数的和，并储存到D中。由于对角线都是1，其倒数也是1，因此求除了对角线的倒数的和，可以先求元胞数组B中每一个矩阵的和，再减去19，因为矩阵为19*19，所以对角线的和为19。

Last week we calculated the inverse of , and this week we perform the next operation, calculating the sum of the inverse of for - except for the diagonal and storing it in D. Since the diagonals are all 1 and their reciprocals are also 1, to find the sum of the reciprocals of except for the diagonals, you can first find the sum of each matrix in the tuple array B and subtract 19, since the matrix is 19*19, the sum of the diagonals is 19.

代码如下图所示：

The code is shown in the following figure.

结果如下图所示：

The results are shown in the following figure.

与之前单独计算的的除了对角线的倒数的和d1相比，可以发现结果相同。

Compared with the previous separate calculation of 's except for the diagonal inverse of and d1, the same result can be found.

03知识补充

A(:)——按线性索引返回矩阵A的所有元素（向量）。

celldisp(a)——显示元胞数组a中各元胞的内容。

如果A是元胞数组，则tf=iscell(A)返回1 (true)。否则，将返回0(false)。

A(:) - returns all elements (vectors) of matrix A by linear index.

celldisp(a) - displays the contents of each element of the tuple array A.

If A is a tuple array, then tf=iscell(A) returns 1 (true). Otherwise, 0 (false) is returned.

今天的分享就到这里了。
