Increase the imaginary part of complex number by a constant in matlab

Question

I think this is a simple question, but I could not find an answer by googling.

Let's say that I have a code like this:

y1=1:0.01:2;

This creates 1x101 long cell, with numbers 1, 1.01, 1.02, 1.03, 1.04, etc. Now I want to have an array of numbers which goes like 1, 1+0.01i, 1+0.02i, 1+0.03i, 1+0.04i, 1+0.05i, 1+0.06i, 1+0.07i, 1+0.08i, etc. I thought that the code 1:0.01i:2; will give the answer, but I am getting a warning

Warning: Colon operands must be real scalars.

How to get around this?

Thanks in advance

Answer 1

As the warning message is trying to tell you, the : is meant to be used in only one dimension. It cannot keep the real part constant and only increase the imaginary part. Instead, do this:

y=0:.01:1;
z=1+i*y

and z will contain the values you want. Here is the relevant docs .
