Assume the formula is A1+B1, and you want to keep B1 fixed for other rows, then use A1 + $B$1
Quite often you need to convert an image (or multiple images) to a MatLab matrix for further analysis and visualization (e.g. extracting time series, multivariate pattern analysis, etc). SPM provides handy functions for this: P = spm_select; % select
Wavelet transform coherence (WTC) is a method for analyzing the coherence and phase lag between two time series as a function of both time and frequency (Chang and Glover 2010). Here I played with it using the MatLab toolbox provided by Grinsted et a
离家不远处有一条静静的小河 闲暇时我和孩子总有一段时光在那儿度过 清清的河水静静地流淌 只偶有几头到河边吃草的老牛慢慢走过 柔顺飘逸的苔丝和水草为小河装点了绿意 一群群小鱼在上面散步跳舞唱歌 思绪像随
Standard deviation (std): standard deviation of the sample Standard error, or standard error of the mean (sem), is the standard deviation of the mean. \(sem=std/\sqrt{N}\) Most errorbars in scientific publications refer to standard error. Quite often
