HI all,
I tried to graph the some data using the following loop i'm new to matlab but i think this is almost right. The only thing is i got this error. Anyone have any ideas? Any help would be appreciated thanks!
fieldNames = fieldnames(MCR_full.MIB035.Reaches);
peakArray
peakArray = 0;
for k = 1 :3(fieldNames)
thisFieldName = fieldNames{k};
thisArray = MCR_full.MIB035.Reaches.(thisFieldName).kin;
x = thisArray(:, 1);
y = thisArray(:, 3);
peakArray{k} = findpeaks(y);
f=figure(k);
plot (peakArray{k});
title(['Peaks for ', thisFieldName]);
end
grid on;
Unable to perform assignment because brace indexing is not supported for
variables of this type.

Instead of
peakArray = 0;
you need,
peakArray = cell(1,numel(fieldNames));

peakArray = cell(1,numel(fieldNames));
and you should have
for k = 1 : numel(fieldNames)
