MATLAB: What does x=val(1,:)

valval(1x=val(1

I should use a Nx1 vector of doubles as my input signal x for my function. What do I get if a use: >>load (´My_Signal.m`) and then >>x =val(1,:); ?

"x" is set to the first row of "val" (thus "x" is a vector of size 1xN where N is the number of columns of "val")

Best wishes

as x is your signal (NX1) vector

minR = 0.15*std(x) ;

Read about std

If your val is a matrix and if it has signal information in the first row, then

x = val(:,1)

should be used....

Read about sub2ind. This should be used for your case.

val = [98 99 100] ; 
idx = sub2ind(size(my_mat),x,y) ; 
my_mat(idx) = val ;
