[SOLVED] Plot functions with MATLAB

[mazdak]

Hi,
how can I plot a function with fplot command while the x axis is semi-logarithmic, i mean the distance between 1 and 10 on the x axis equals to distance between 10 and 100. the semilogx command plots that way but it won't accept functions.
any ideas?

I don't know how to modify x axis in fplot.

I think the simplest way is to use semilogx function. Because semilogx doesn't accept function, we must set input variable and call the function manually before using semilogx.

You have to edit "fplot" function then,
change the instruction plot(xx,y,marker,'parent',cax) to semilogx(xx,y,marker,'parent',cax)
that's all
