error using preallocation for table using size option in R2023b

h=table('Size',[ 2212 5],"VariableTypes",{'double','double','double','double','double'});

Error using table

You might have intended "VariableTypes" to specify a parameter name. However, the table constructor requires parameter names to be

specified as character vectors. Use table(..., VariableTypes=Value) or table(..., 'VariableTypes', Value) instead.

Use single quotation marks around the VariableTypes arguement instead of double quotation marks -

%                       v             v
h=table('Size',[2212 5],'VariableTypes',{'double','double','double','double','double'})

h = 2212x5 table
