达到固定值时将向量转换为矩阵 [英] Turn vector into matrix when a fixed value is reached
本文介绍了达到固定值时将向量转换为矩阵的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
此问题是对此问题的补充:链接到原始问题 我该如何在代码中实现,所有行都应填充"为0,例如第6列.
This question is an addition to this one: Link to original question How can I implement in the code, that all rows should be "filled up" with 0 let's say up to column 6.
这是它应如何工作的示例.
This is an example of how it should work.
V [18x1]: [6000, 6500, 5000, 8000, 15000, 15500, 16000, 6000, 4000, 16500, 14000, 400, 5000, 6000, 9000, 12000, 13000, 5000]
Matrix [3x4]:
1.row [8000 15000 15500 16000 0 0]
2.row [16500 14000 0 0 0 0]
3.row [9000 12000 13000 0 0 0]
推荐答案
您应修改答案,如下所示:
You should modify the answer likes the following:
result = []; new_row = 1; col_num = 1; row_num = 0;
limit = 7000;
for idx = 1:length(V)
if col_num == 7
new_row = 1
end
if(V(idx) > limit && new_row == 0) % case 1
result(row_num, col_num) = V(idx);
col_num = col_num + 1;
elseif(V(idx) > limit && new_row == 1) %case 2
row_num = row_num + 1; new_row = 0; col_num = 2;
result(row_num, 1) = V(idx);
elseif(V(idx) <= limit) %case 3
new_row = 1;
end
end
if size(result,2) < 6
result(1,6) = 0;
end
添加以下行以检查col_num
不超过6
:
Add the follwoing lines to check the col_num
does not exceed from 6
:
if col_num == 7
new_row = 1
end
最后,检查result
的列大小是否不是6
,修改result
矩阵,如下所示:
At the end, check if the column size of the result
is not 6
, modify the result
matrix likes the following:
if size(result,2) < 6
result(1,6) = 0;
end
