How to make a loop to average the values?

Hi guys,

I have written

BV_14_L_mean = mean(BV_14_L,2);

BV_14_L_std = std(BV_14_L,0,2);

BV_16_L_mean = mean(BV_16_L,2);

BV_16_L_std = std(BV_16_L,0,2);

BV_18_L_mean = mean(BV_18_L,2);

BV_18_L_std = std(BV_18_L,0,2);

BV_20_L_mean = mean(BV_20_L,2);

BV_20_L_std = std(BV_20_L,0,2);

BV_22_L_mean = mean(BV_22_L,2);

BV_22_L_std = std(BV_22_L,0,2);

BV_L_mean_graph = errorbar(BV_14_L_mean,BV_14_L_std,'-','LineWidth',2)

view([90, -90])

hold on

errorbar(BV_16_L_mean,BV_16_L_std,'--','LineWidth',2)

view([90, -90])

hold on

and so on..

I would like to make the codes below shorter by using a for loop.

BV_14_L_mean = mean(BV_14_L,2);

BV_14_L_std = std(BV_14_L,0,2);

so on

BV_14_L to BV_22_L are 10*5 doubles.

How should I do it?

If you want to use a for loop, you can do this

for j=14:22
    eval(sprintf('BV_%g_L_mean = mean(BV_%g_L,2);', j, j));
    eval(sprintf('BV_%g_L_std = std(BV_%g_L,0,2);', j, j));
end

Hi Yazan, thanks for your answer. As my data is 14,16,18 -- how should i change the %g so that it adds up by 2 each time up to 22?

Just modify the looping

j=14:2:22

Oh right that was a pretty stupid question. Thank you!
