I studied a code related to my work in which there used a for loop.as given
for jcyc=3:3:57;
[ddx, cycl_ind(jcyc)]=min(abs(jcyc-time_2));
end
here time_2=1×1800.in square bracket the function of ddx and cycl_ind(jcyc) is not clear to me.I mean on the left side for which purpose the square bracket and inside it ddx, cycl_ind(jcyc) is used.?

@ SAFI ULLAH: you are asking questions that are very basic MATLAB syntax. These topics are covered very well in the introductory tutorials:

min() returns, or can return two outputs. If you accept more than one of the outputs, you need to group all the outputs together with brackets, otherwise it would be interpreted as two separate lines of code on the same line (you can put multiple commands on the same line if you separate them with commas).
The documentation says the first variable is the min value, and the second variable is the index where the min occurs.
