I have a plot for 6 different line equations. I have plotted these with 6 different color, but in the plot, in legend location the colors are coming out of the order in which they were plotted. Please help if anyone knows how to correct this problem.

Did you plot a 2D matrix, or did you call plot 6 different times with 6 different vectors?

To be more specific, if I have- plot(x,y1,'k', x,y2,'b', x,y3,'m'); then using legend as- legend('eq1', 'eq2', 'eq3'); should indicate black color as eq1, blue as eq2 and magenta as eq3. But it isn't.

This is the expected behavior of the legend function. If you want another order, the simplest way is to change the order of plotting the equations. If you do not tell us what you want to achieve, we cannot guess how to 'correct' the correct behavior of a function.

For me this works as expected:
x = 1:100; y1 = x; y2 =2*x; y3 = 3*x;plot(x,y1,'k', x,y2,'b', x,y3,'m')
legend('eq1', 'eq2', 'eq3')

It works fine for me. I'm using R2015b. What version are you using? Can you post a screenshot?
