convert string to number in a matrix

I have a matrix, but I found there is a error, some numbers are recognized as char. I want to convert these chars to number. Is there any good method?

What data type is your matrix? Is that a cell array in which we should assume that each numeric value is a 1 x 1 numeric cell?

Please attach the data file from which you got these along with the code you used to read it in.

Along IA's request, look at

doc detectImportOptions

and the appropriate XXXImportOptions object for spreadsheet or delimited text linked to therein. In that import object you can then set the data format for variables not recognized automagically and pass that to the readtable function to import the data correctly.
