Hello all. I am attempting to translate a MATLAB file that evaluates a
string column by column. The function is simple, pasted below:
function y = mapcol(text,p0,p1,p2)
%MAPCOL
% mapcol(STRING,A,B,C) will execute the command
% contained in STRING over the columns of the matrix A,
% creating one column of the output matrix at a time.
% The additional arguments B and C are available to pass parameters.
% EX: mapcol('x.*p1',A,b) will do a point-wise
% multiplication of each column of A by the vector b.
%
[M,N] = size(p0);
y = [];
for i=1:N
x = p0(:,i);
y(:,i) = eval(text);
end
In trying to write the equivalent function in Julia, I ran into issues
regarding eval() only having access to variables at the global level. Is
this possible to translate?/ How would I go about doing so (preferably
without too much added complexity, which I noticed in other threads
regarding the scope of eval)? I realize that this function may not appear
to be very useful on the surface, but for me it would be worth having as a
tool to use in other functions.
Any feedback is appreciated. Thanks.
