Impossible to do an indexing

Hi everyone,

I've imported an EMG signal named soleus and I want to find the position of the stimulations (stim and stim_Hz) on that signal.

It's always working except this time were I have this error message: "Array indices must be positive integers or logical values."

soleus 1683210x1 double,

stim 82x1 double,

stim_Hz 82x1 double

>> load('LV+Hreflex.mat')

>> soleus = LV_Hreflex_Ch7.values;

>> stim = LV_Hreflex_Ch10.times;

>> stim_Hz = stim*4000;

>> soleus(stim_Hz)

Array indices must be positive integers or logical values.

Thanks!

I suspect the problem is with:

soleus(stim_Hz)

Here, ‘stim_Hz’ must be either logical, or integers greater than 0. There are a number of ways to convert non-integer numbers to integers (for example ceil, others are linked to in that page), and comparisons to a value will prodice a logical vector.
