hello, i m facing problem to plot all columns of an array in same plot inside for loop.what my code doing is it's executing the value of last column of desired array.the array columns should plot curves for y axis.in code array - 'fxl'

Use hold on after the plot.
Or you can save all your data into a amtrix and plot at once.
