This function definition is invalid. I guess the rules for function
names are the same as for variables: ... The name of a variable must be
a sequence of letters, digits and underscores, but it may not begin with
a digit...

Try function [newXY] = MinuOrigin_TransAll(real_end, k) instead

I guess you haven't called mark_minutia with arguments. See this example

function b=square_it(a)

octave:3> square_it(3)
ans =  9
octave:4> square_it()
error: 'a' undefined near line 2 column 3
error: called from:
error:   square_it at line 2, column 2

Do you see? The second call was without argument and therefore a is
