how to merge one column dataset into big dataset file

i am importing big excel file with dates and data into MATLAB. i am using MAC while the Excel is imported to matlab the dates column is corrupted. i sucsses fixing the corrupted dates in different dataset column. now i wanted the replace the corrupted dataset dates column with the fixed one and merge it to the all other data. how can i do it?

for example:

ds1= all data imported from the excel file and transform into dataset, but in this file the first column is the dates with the corrupted dates. Size of ds1 = 373x14 ds2 = this is only one column with the fix dates. Size of ds2 = 373x1

how i merge ds2 into ds1 and keep them stay as dataset?

As the rows in ds1 and ds2 are same. You can replace the first column or merge easily.

Replace:

ds1(:,1) = ds2 ;  % replaces corrupted dates with corrected dates

the two ds are the same length. now i got this error from Matlab:

Error using dataset/subsasgnParens (line 133) Subscripted assignment dimension mismatch for dataset variable 'Date'.

Error in dataset/subsasgn (line 79) a = subsasgnParens(a,s,b,creating);
