How do I add an array to a table?

I already tried the matlab function arratotable. The error that I have is that the array is not of the same dimension of the table. How can I fix this problem ?

If you're adding a new column of data to an existing table, the column must have an equal number of elements as all other columns of data in the table. One way of achieving that is by padding the shorter column(s) with NaN values (or some other default value).

Often times it's easiest just to pad values to the end of a column using [x; NaN(sz)] but there are functions that may come in handy such as B = padarray(A,padsize,padval).

If you have any problems implementing this method, show us your code and we can help straighten it out.

Yes I am having problems

I need to make some math equation that is always one row less than the others how can I add just one NaN value at the end of the array?

acel {i,1} = v / t

A = array2table (acel)

" how can I add just one NaN value at the end of the array?"

It's not clear how the 2 lines of code fit into that question. But to add one NaN to the end of a numeric row or column "v",

v = [v,nan]; % if v is a row
v = [v;nan]; % if v is a volumn

If that doesn't help, you'll have to provide more detail.

Thanks. It works. Do you know how to make the sum of a value from a table and another in a cell array?

rel = v(i) + e{i}

What is the size of the array? And of the table you expect to get?

Do you want to split up the array so that each column or row goes into one column of the table? Like you have an N-by-3 matrix and want each column of that to go into individual columns of the table.

OR do you want to have each element of the table contain the complete array, for example row 1, column 2 (or whatever) contains a 3-row-by-5 column matrix, and all other rows in that column 2 would also contain other 3x5 matrices as well? (Similar to what the example in the help shows for blood pressure.)

This isn't clear to me. Could you give an example?
