The first thought was that I need a string array that was indexed. I thought I could do something like: fori=1:n char(i)=('Help'num2str(i)); end but this is not working. It will to accept the indexed number and the string. together, although the code without the text works fine...
but also readable and expressive. Matrices are a core component of MATLAB for organizing and analyzing data, and indexing is key to the effectiveness of manipulating matrices in an understandable way.
MATLAB "is" functions also return logical arrays that indicate which elements of the input meet a certain condition. For example, check which elements of a string vector are missing using theismissingfunction. str = ["A""B"missing"D""E"missing]; ind = ismissing(str) ...
I need to convert 'CodeTimes' within 'BehavioralCodes' in each trial (each trial is saved individually like trial1) from a string to an integer. I have tried: code_times = str2num('CodeTimes') but that gives me an empty array so I am definitely doing something wrong. ...
主要错误是没有正确理解使用diff（）函数。diff（f(x),a）要求f(x)是一个具体的函数，a是一个数值而不是一个数组。所以你写的dh=diff(h,a)是有问题的。根据你的问题，将代码重新改写（如下）后，运行得到
syntax errors. In MATLAB, when calling a function or indexing an array, you need to use parentheses appropriately. To correct

Open in MATLAB Online code: ThemeCopy [IMF, residual, info] = emd(eeg_signal); imf_count = max(info.NumIMF); Dot indexing is not supported for variables of this type. 1 Comment Komal on 23 Nov 2023 Thanks a lot sir. Sign in to comment...
Open in MATLAB Online Hi @Lea Kerciku, To save the trials numbers in a vector you can use “cell2mat” function. ThemeCopy % Load the Excel table containing rejected trials rejected_trials = xlsread('path_to_your_excel_file.xlsx'); % Extract the trial numbers for reject...
