Why wouldn't this work:
if isfile(filename)
delete filename
end
filename is a char vector.
File is not deleted, and I get a warning: Warning: File 'filename' not found.
How could it be not found if isfile returned true? Am I doing some beginer mistake?

"Why wouldn't this work: "
Because you are using outdated, misleading, sadly overused command syntax.
Use function syntax instead.

Look at the example,
delete *.mat
That is not going to ask MATLAB to look at all variables that are in scope and see if they are structs with field named mat, or objects with property named mat, or objects with method named mat, and then evaluate as appropriate in order to get the names of the files to delete. NOT done.
Instead it is treated as
delete('*.mat')
which tells it to delete all files in the current directory whose extension is .mat
