Exporting table to excel

Good Afternoon, I will try to keep this to the point. I have created two tables and they ready to be exported to excel. Say T1 is [1600x5] and t2 is [2x4]. How can I concatenate those two tables into one so then I will be able to use the "writetable" function? I have tried the "horzcat" and the "union" functions but I keep getting errors due to the dimensions not being the same. Is there a way around this?

Date = datetime('today'); M1 = table(Temp_K, Pressure, inverse_temp, N_Log, k_value_slope); (1600x5) Matrix M2 = table(MM, Date, Pan_Size, Experiment_Date); (2x4) matrix M = horzcat(M1, M2); M = table(Temp_K, Pressure, inverse_temp, N_Log, k_value_slope, MM, Pan_Size); name = input('Enter the name you wish to save the file as, use single quotes (ex. filename.xlsx) : '); writetable(M, name,'Sheet',1,'Range','B1');

use blkdiag(A,b) .

I have tried this and still returns an error.

1. x=[1 2 3 6 ;4 5 6 51 ;7 8 9 2 ;10 11 12 11];
2. y=[4 5 6;7 8 9];
3. C = blkdiag(x,y);
4. C(1:2,5:7)=y;
5. C(5:6,:)=[] . thus [4*4] & [2*3] can be concatenated , or any other dimensions as well.

You don't have to join tables before exporting them. You can just create spreadsheet and then add other data in other sheets or in the same sheet, specifying target cells.

Maybe you would like separate sheets?

   warning('off','MATLAB:xlswrite:AddSheet'); %optional
   writetable(M1,'test.xlsx','Sheet',1);
   writetable(M2,'test.xlsx','Sheet',2);

Or in one sheet:

   writetable(M2,'test2.xlsx','Sheet',1);
   writetable(M1,'test2.xlsx','Sheet',1,'Range','E1');

Thank you very much!! For some reason I thought I had to joint both tables before using the writetable function.

Hello, how do you save the excel file (test.xlsx) in a specific directory. Thanks

[Daniel]

You can specify the directory in 'test.xlsx'.

writetable(M1,'C:\Users\JohnDoe\Documents\MATLAB\test.xlsx','Sheet',1);

You can find the working directory using pwd.

S = pwd + "\test.xlsx"
writetable(M1,S,'Sheet',1);

Replace S with the filepath and filename.
