I don't what is wrong with this coding..Pls help me identify

I want to give signals in polar form...First I create random data and then use If condition to change it to polar form

len=128;

m=4;

msg1=randint(len,1,m);

msg2=randint(len,1,m);

if msg1(1,1)=0

polar_data=-1;

else

polar data=1;

end

if msg2(1,1)=0

polar_data2=-1;

else

polar data2=1;

end

Error:The expression to the left of the equals sign is not a valid target for an assignment.

In your if statements you need to use the symbol "==" rather than "=" to check equality.

There are a couple other errors in your code. For example, you have the line

polar data=1;

which I think you meant to be

polar_data=1;

Below, I fixed up a couple of those:

len=128;

m=4;

msg1=randint(len,1,m);

msg2=randint(len,1,m);

if msg1(1,1)==0

polar_data=-1;

else

polar_data=1;

end

if msg2(1,1)==0

polar_data2=-1;

else

polardata2=1;

end

I want all my random values to be converted to polar form

I get only one value from this coding..what should i do?

[Oleg Komarov]

Don't do that!

@Srinivas, did you really read the faq?

[Janet]

pls anyone help me to use for loop

[Srinivas]

just do avoid confusion I deleted my previous comments.

@sana, you can use 'for' loop and link below should help
