I feell like my code is too long for what it is trying to do... I wrote a function that calculates a sigmoid function which is fine... with this code:
function [ yValues ] = sigmaFunc( data,a,b )
yValues = zeros(size(data,1),size(data,2));
for ii = 1:length(data)
yValues(ii) = a/(1+exp(-b.*data(ii)));
end
and then I was requested to write a function with no input/output data that calculates 3 sigmoid functions with same a&b but with different x-data - I thought that using a loop in this case is not so efficient, but now I feel like my code is too long - can you think about ways to do the same with less lines? since I cannot think of anything :(
a=4;
b = 0.5;
xDatai=-50:0.5:50;
[ yValues ] = sigmaFunc( xDatai,a,b );
subplot(3,1,1);
plot(yValues,'k');
xlabel('1st x data');
ylabel('1st y results');
title('Sigmoid Graph - increment =0.5')
ylim([0 6]);
xDataii = -50:5:50;
[ yValuesi ] = sigmaFunc( xDataii,a,b );
subplot (3,1,2);
plot(yValuesi,'k');
xlabel('2nd x');
ylabel('2nd y results');
title('Sigmoid Graph - increment =5');
ylim([0 6]);
xDataiii= -50:10:50;
[ yValuesii ] = sigmaFunc( xDataiii,a,b );
subplot(3,1,3);
plot(yValuesii,'k');
xlabel('3rd x');
ylabel('3rd y results');
title('Sigmoid Graph - increment =10');
ylim([0 6])
end
