Hi there I am using a custom-made Matlab s-function script which demands that I know how large my output data is before I intialise it. The problem is I want this to be chosen by a variable rather than me having to manually open the file and change it.
What I need to know is how to go about running an .m script file which does the following:
open another .m file
looked down to the n-th line of this file
replace the first number it finds on this line with one from a variable i choose
save and close the file ready to be run
I want this to be done all within matlab so i can simply run a script to do this.
Would anyone know how I can go about doing this? perhaps a suggestions of a command for each of the steps I need?
I have read into textread but that seems to want to read each word on the line into a seperate variable. Even then, I cant figure out how to write the new value back to the .m file.
