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)
