How to calculate mean and standard deviation for loops?

7 views (last 30 days)
story_Acc_FN_UL0_S1_5 = randn(1,10);
story_Acc_FN_UL0_S2_5 = randn(1,10);
story_Acc_FN_UL0_S3_5 = randn(1,10);
story_Acc_FN_UL0_S4_5 = randn(1,10);
story_Acc_FN_UL0_S5_5 = randn(1,10);
for uu = 1:10
story_Acc_FN_UL0_R_rup_5(1,uu) = mean(story_Acc_FN_UL0_S1_5(1,uu),story_Acc_FN_UL0_S2_5(1,uu),story_Acc_FN_UL0_S3_5(1,uu),story_Acc_FN_UL0_S4_5(1,uu),story_Acc_FN_UL0_S5_5(1,uu));
std_dvt(1,uu) = std(story_Acc_FN_UL0_S1_5(1,uu),story_Acc_FN_UL0_S2_5(1,uu),story_Acc_FN_UL0_S3_5(1,uu),story_Acc_FN_UL0_S4_5(1,uu),story_Acc_FN_UL0_S5_5(1,uu));
end

You don't need to use loop for that. You can use cat command to concatenate, and then use mean and std functions to the matrix itself.
story_Acc_FN_UL0_S1_5 = randn(1,10);
story_Acc_FN_UL0_S2_5 = randn(1,10);
story_Acc_FN_UL0_S3_5 = randn(1,10);
story_Acc_FN_UL0_S4_5 = randn(1,10);
story_Acc_FN_UL0_S5_5 = randn(1,10);
matrix=cat(1,story_Acc_FN_UL0_S1_5,story_Acc_FN_UL0_S2_5, story_Acc_FN_UL0_S3_5, story_Acc_FN_UL0_S4_5, story_Acc_FN_UL0_S5_5)
matrix = 5×10
0.5803 0.2545 1.3201 1.1169 1.1713 0.6641 0.6268 0.1792 0.5207 -0.8742 0.2123 -1.1177 -0.7340 -0.4116 1.6859 0.4254 -0.0838 -1.3029 0.2514 -0.0004 -0.1874 -1.3762 0.4546 -1.2224 0.4418 1.2452 0.7849 2.4942 -0.3359 -0.7775 -0.5222 2.1919 -0.1692 0.7816 0.0996 0.9557 -0.5402 0.5236 0.8086 -0.5950 1.0547 0.4665 -0.0449 0.7405 -0.2555 -1.1399 0.4181 -0.7332 -2.2922 1.3358
meanvalue=mean(matrix)
meanvalue = 1×10

stdev=std(matrix)
stdev = 1×10
