I ran the code to output a large matrix(59107200*10) to a csv file and got this error. The script: dlmwrite('fullbrain.csv',fullbrain); Any solutions and reason why this error? Or, are there any better solutions to output a large matrix to a csv file?

You need to use the fopen command to create a valid file identifier, you can then write code to the file and fclose it after.
