First column represent x axis, second and third column represent y-axis, want to generate plot with x axis as the values are there and y axis for second column and above that plot the y axis for third column? how can it be?

If s is your matrix
x=s(:,1);
y1=s(:,2);
y2=s(:,3);
plotyy(x,y1,x,y2)

do you mean this? your question is not very clear.
figure; hold on;
a = subplot(2,1,1); plot(y1,x);
b = subplot(2,1,2); plot(y2,x);
linkaxes([a b],'x');

you cannot have two y axis in a single figure. you could have subplots, each with one x axis and one y axis. in each subplot you can plot as many curves as you want. you could do that like this:
figure; subplot(1,2,1);
hold on;
plot(y1,x, 'r');
plot(y2,x, 'b');
.
.
.
plot(y1000, x, 'k');
hold off;
subplot(2,1,2);
hold on;
plot(yy1,x, 'r');
plot(yy2,x, 'b');
.
.
.
plot(yy1000, x, 'k');
hold off;
you could use different colors (specified by 'r' & 'b', etc) for each plot. see and read more in:
help plot

How can I overcome this error ?
??? Undefined function or method 'parseArgs' for input arguments of type 'cell'.
Error in ==> samexaxis at 33
Args=parseArgs(varargin,Args,{'abc' 'join' 'ytickanticlash'});

Matlab cannot find your function "parseArgs". You should put it in the same folder as your running script, or add its path in: File -> Set Path... .
