How to add rows to an existing table

Hi

I am trying to add rows to this existing table, however I can't seem to add any, the one row just gets changed to the new value.

    1×7 table

       Neuron     Neuron_ID    NoSynapses    SynapticDensity    NoBranches    BranchDensity    Clustering
      ________    _________    __________    _______________    __________    _____________    __________

      'ipsiCN'    [5]          [2]           [4.0060]           [12]          [0.0482]         [0]

Does anyone have any help on this?

Cheers

There are many ways to do this. There's documentation on all the various ways to use subscripting on a table, that would be a good place to start.

The most generic answer would be, "How would you add rows to any array in matlab? Do it like that." Hard to be more specific without some idea of what you are doing now.

A link to this particular documentation for this particular question would be helpful. I have been looking all around for this exact same thing but... ended up here as well as not being able to find the answer.

Fitting to this format where 'A', 'B', etc.. are your values of Neuron Neuron_ID etc.

C = {1,2,3,4}

T = cell2table(C,'VariableNames',{'A','B','C','D'})

T1 = table(5, 6, 7, 8,'VariableNames',{'A','B','C','D'})

Tout = [T;T1]

Basically you are creating one Table T from cell2table and then creating the table T1 and Matlab matches the 'variableNames' together. NOTE 'variableNames' is a keyword, it is not an arbitrary name, also that the actual number of and string names such as 'A' 'B' 'C' and 'D' MUST match between the two tables.

The post which I modified the above from is here: Adding Rows to Table

T = table([10;20],{'M';'F'},'VariableNames',{'Age','Gender'},'RowNames',{'P1','P2'})
Tnew = table(30,{'F'},'VariableNames',{'Age','Gender'},'RowNames',{'P3'}) ;
T = [T ; Tnew]
