Hello
I am trying to use the max function, but it will not work. I have attached my log file.
I have tried using this function
maxStcev=max(Stcev'-K,0); %(line 52)
but I keep getting negative values.
I have then tried using a for loop with if statement, but this results in error:
"Index exceeds matrix dimensions.
Error in mccev (line 45)
if (M1(1,o)<0)"
Can someone see what I am doing wrong? I want t have a vector only with positive values.
Regards,
Søren

Hi Søren
I could not view the log file attached, and I am not very sure about the workflow taken by you. Generally, the "Index exceeds matrix dimensions" error occurs when elements outside the bounds of valid indices are being accessed. The variable "o" in the above example could be greater than the matrix dimension at some iteration in the loop. Please make sure it is within the matrix dimensions.
If you want to simply separate out the positive values from a vector, you could do something like:
>>x=[6 5 -2 3 -7]
>>y=x(x>0)
Hope this helps!
