为什么在尝试使用vertcat时出现错误？
[英]Why am I getting an error when trying to use vertcat?
问题描述
I'm getting an error when trying to use vertcat to concatenate two matrices. 
尝试使用vertcat连接两个矩阵时出现错误。 How can I concatenate this matrix 如何连接此矩阵
text =
Columns 1 through 6
'GL/GG' 'go' 'vc (m/min)' 'fz (mm)' 'Fx (N)' 'Fy (N)'
'[]' '[]' '[]' '[]' '[]' '[]'
Columns 7 through 9
'd (°)' 'MA (%)' 'V (%)'
'[]' '[]' '[]'
which is 2-by-9, with another matrix that includes double values and is 96-by-9. 它是2×9，另一个矩阵包含双精度值，是96×9。
I don't understand why there is a problem with this vertcat function. 我不明白为什么此vertcat函数有问题。 As far as I can tell, c = vertcat(text,text) works fine: 据我所知， c = vertcat(text,text)可以正常工作：
Columns 1 through 6
'GL/GG' 'go' 'vc (m/min)' 'fz (mm)' 'Fx (N)' 'Fy (N)'
'[]' '[]' '[]' '[]' '[]' '[]'
'GL/GG' 'go' 'vc (m/min)' 'fz (mm)' 'Fx (N)' 'Fy (N)'
'[]' '[]' '[]' '[]' '[]' '[]'
Columns 7 through 9
'd (°)' 'MA (%)' 'V (%)'
'[]' '[]' '[]'
'd (°)' 'MA (%)' 'V (%)'
'[]' '[]' '[]'
What should I do? 我该怎么办？

You can only concatenate vertical arrays (of type string) if they are the equal size ie the rows and columns must be identical. 如果垂直数组的大小相等，即行和列必须相同，则只能将它们连接起来。 A similar question was answer here - https://math.stackexchange.com/questions/449791/why-do-i-keep-getting-a-vertcat-error-in-matlab . 在这里回答了一个类似的问题-https: //math.stackexchange.com/questions/449791/why-do-i-keep-getting-a-vertcat-error-in-matlab 。 May be this will help you understand what you are up against? 也许这可以帮助您了解自己所面对的问题？
A tip for you would be to pad the difference using white-space " "? 给您的提示是使用空格“”来填充差异？ This will make sure that you have an equal size array to work with. 这将确保您具有相等大小的数组。 HOwever, I don't know the parameters of your operation, so using " " as a padding element may affect what you are trying to achieve. 但是，我不知道您的操作参数，因此将“”用作填充元素可能会影响您要实现的目标。

The problem is that your text matrix is in fact a cell array where as your matrix of doubles is just a regular double matrix. 问题在于您的text矩阵实际上是一个单元格数组 ，其中作为双精度矩阵的矩阵只是一个常规双精度矩阵。 In order to do the concatenation you first need to convert your array of doubles to a cell array where each element is in a separate cell (ie a 96 -by- 9 cell array). 为了进行串联，首先需要将双精度数组转换为单元格数组，其中每个元素都位于单独的单元格中（即96 x 9单元格数组）。 To do this you use mat2cell : 为此，您可以使用mat2cell ：
text = { 'GL/GG', 'go', 'vc (m/min)', 'fz (mm)', 'Fx (N)', 'Fy (N)', 'd (°)', 'MA (%)', 'V (%)';
'[]', '[]', '[]', '[]', '[]', '[]', '[]', '[]', '[]'};
num = rand(96,9);
vertcat(text, mat2cell(num, ones(size(num,1),1), ones(1,size(num,2))));
