-=== Purpose ===
+#REDIRECT [[localmaxima]]
-Automated identification of local maxima.
-===Synopsis===
-:i0 = localmax(x,w)
-===Description===
-Finds maxima in windows of width (w). Wider windowing is used to avoid local maxima that might be due to noise. The default window width is w=3. This function is called by PEAKFIND.
-====Inputs====
-* '''x''' =   matrix of measured traces containing peaks each   row of (x) is an individual trace.
-====Optional Inputs====
-* '''w''' = odd scalar window width for determining local maxima {default: w = 3}.
-====Outputs====
-* '''i0''' =   cell w/ indices of the location of the major peaks for each of the   traces in each cell.
-===Examples===
-<pre>load nir_data
-plot(spec1.axisscale{2},spec1.data(1,:))
-i0 = localmax(spec1.data(1,:));
-vline(spec1.axisscale{2}(i0{1}))
-i0 = localmax(spec1.data(1,:),5);
-vline(spec1.axisscale{2}(i0{1}),'r')</pre>
