Global Threshold on the Excel File

Hello everyone.

I have a grid excel file with 300x300 pixels (cell). Each pixel represents different intensity value range from 0 to 0.1. I would like to threshold this grid so that any pixel value lower than 0.04 will be equal to 0. Does anyone know how to do that.

Thank you.

I'm assuming you've loaded the file into MATLAB. Use logical indexing to set any value less than 0.04 equal to zero.

Data(Data<0.04)=0;
