How to use one conditions's result in to another condition?
显示 更早的评论
Hello. I am facing some problem with Matlab coding. I want:
if working_mode == 1
a = func_con(x);
save a;
else %%%Here, i want to use the value of "a"
a;
for i = 1:3
if a > 10
a = func_rep(a);
else break,
end
a;
end
end
How can i perform this operation? Any help will be appreciated. Thanks.

Hi,
if a doesnt exist than you cant use it. But you can use ifempty to check if the variable a is filled with data, e.g.
a = [];
if working_mode == 1
a = func_con(x);
save a;
else %%%Here, i want to use the value of "a"
if ~isempty(a)
a;
for i = 1:3
if a > 10
a = func_rep(a);
else break,
end
a;
end
else
disp('a doesnt contain data')
end
end

You can also use
exist(a,'var')
to check if a variable exists in the current workspace
