How to read the variable named sigma0 from multiple datas by using a loop ,where the datas are in h5 format?

1 回表示 (過去 30 日間)
Dataloc= '/home/ecsa_aleena/desktop/data cd(dataloc) Filename='/home/ecsa_aleena/desktop/data Dataset_name = 'science_data' Allfiles=dir(E06SCTL2A2023068_*.h5') Len =size(allfiles,1); Var=h5read(allfiles,'science_data/Sigma0');
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses.
But the var command is showing error or is there other codes for creating a loop for finding the nanmean or mean of sigma0 for the multiple datas?

No, you do not get as far as the var command. Your code has invalid syntax, with a lot of places you do not close quoted strings.

MATLAB is case sensitive. Allfiles and allfiles are not the same thing.
Also, the first input to h5read must be a single file name, not a structure. If you have multiple files you would like to read in, I suggest looking into a filedatastore to load all the data into a single variable. You can see an example of how to use one to do this in this video from the Data Processing with MATLAB specialization on Coursera.

So while using h5read,how can i add 52 datas altogether,as i need the mean of these 52 datas? Is there any code for that

Add whatever processing you want to do to each file to your import function.
Here, that would mean having your import function read in the desired variable from the current file, then take the mean and assign that to the function output variable.
Write the code for a single file, then wrap it all up in a function, and use that as your import function.
