Save the table to a specific folder

I use this code to save the matlab table. When I run the code, it is done proerly but no table is found at the folder. Any idea?

save_table='C:\Users\imagej output\set test\ImageJ_Result_PostProcessing';
table_path_format = [save_table 'T.xlsx'];
writetable(T,table_path_format);

Thank you

Answer 1

table_path_format = fullfile(save_table, 'T.xlsx');

Answer 2

[Bhaskar R]

table_path_format = [save_table '\T.xlsx'];
% you forget to put accurate path that is \ operator
% or correct way is to use fullfile table_path_format = fullfile(save_table,'T.xlsx');

\ is a text character in that context, not an operator. \ is a "directory separator" at the operating system level; https://en.wikipedia.org/wiki/Path_(computing)
