array slicing in Matlab

Hello everyone,

I tried to slice my data from the from position where threshold is crossed to end of window using Python and I worked but when I tried to write it in matlab, Unfortnetly I encountred some errors.

Python code:

for i in pos:
    if i < data.shape[0] - (SW+1):
        Waveform = data[i:i+SW*2] 

Matlab code:

        for i=1:length(pos)
            if  i < (data - SW+1);
                WF = data(i,i+ SW*2);
            end

        for i=1:length(pos)
            if  i < (data - SW+1);
                WF = data(i:i+ SW*2);
            end

Looks like a set of parens is missing also:

(data - (SW+1))

Hi,

MATLAB Version of the code would be

sizeOfData = size(data)
for i=1:length(pos)           
            if  i < (sizeOfData(1) - (SW+1));     %% use size function to get the size of the matrix
                WF = data(i:i+ SW*2);
            end 

size function returns a vector of number of elements in the row and column.
