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)
