I have a function which makes a plot from different vectors, then each time that I add a new plot I need to add a new legend which is a variable(legend) now I trying to do it with the next code:
plot_test = plot(vector1, vector2, '-mo','Color',color, 'DisplayName',legend);
hold all;
legend('-DynamicLegend');
but as result I got two new legends for each plot, one whith the real name and another called line2, line4, line6....and so on depending the number of plots...
Any help please?

Look at this example
x=0:0.1:10;
y1=sin(x);
plot(x,y1)
hl=legend('leg1')
hold all
y2=cos(x)
plot(x,y2)
leg=[get(hl,'string'), 'leg2']
hl=legend(leg)

Add to your input and output argument of your function the handles old_hl and hl

Is this the type of feature your after:
figure;
x = [0:0.01:2*pi];
hold on;
plot ( x, sin (x), 'DisplayName', 'Plot A' )
legend ( '-dynamicLegend' )
plot ( x,- sin (x), 'r', 'DisplayName', 'Plot B' )
plot ( x, 2*sin (x), 'g', 'DisplayName', 'Plot C' )
