Summary of above discussion - the error message Number of case names must equal number of data rows is indicating that there is a discrepancy between the number of elements in rownames11 and the number of rows in data. Just prior to calling tblwrite, the following was typed in the Command Window
size(values11)
size(colnames11)
size(rownames11)
to determine the size of each cell array. As Ahmed posted, the sizes were: Values11 is 1x225 but it is cell contain 6 values Rownames is 1x6 colnames is 1x225.
The solution was to set Values11 to a numeric matrix with 6 rows and 225 columns, rather than using a cell array
Values11 = zeros(6,225);
for …
rownames11{kk}=char(rownames1(1,j));
colnames11={'K_minus_t';'K_minus_d';'a';'b';'c';'Err'};
values11(:,kk)=[K_minus_t(j) K_minus_d(l) c resnorm]';
end
Note how the last line (in the above) sets the kkth column to a 6x1 vector (the apostrophe was added to transpose this to a column vector).
tblwrite can then be called but must make sure that the second and third inputs are correct - since Values11 is 6x225, then the second input must have 225 strings, and the third input have six strings.
