# MATLAB: What is wrong with the code short simple function using only – if,for,length and variables)

for loopfunctionifMATLABvariable

I needed to write a function that uses only if for length and variables and calls another function – valFind(that runs very well-added below), my function gets:1) a vector 2)an arrays of numbers to search for and brings back the first places in which those numbers appear in the vector (or 0 if they don't appear) for example:
    % codea=[2 4 6 8 4 2]b=[2 8 9]c=valFindAll(a,b) --> [1 4 0]
this is valFind (runs fine the problem is in the text function)
    % codefunction [result] = valFind(a,b)result = [];for ii=1:length(a)    if a(ii) == b        result = [result ii];end end
this is the function that (I don't know why) doesn't run
    % codefunction [resultVec] = valFindAll(a,v)resultVec =[];for ii=1:length(v)  [result]=valFind(a,v(ii));  if result == []      resultVec = [resultVec 0];  else      resultVec = [resultVec result(1)];  endend

result == []
length(result) == 0
