I am creating a function that needs to have a couple of values associated with a file that it loads and does some processing to. The function looks like this (obviously names changed.)

function [outx,outy] = imstupid(image_filename,var1,var2,var3)
G = imread('filename','bmp');
.Functions
.That
.Already
.Work
end

Sorry if this isn't clear, but basically I need to have image_filename be called as text value that is used in the imread function. Thanks!

在 MATLAB Online 中打开

Assuming image_filename contains the complete path (if not on matlab path) or name of image to be read, then

G = imread( image_filename);

Just a minor note, when inputting the image_filename variable, one needs to make sure to include the format as 'image_filename.format' syntax or else there will be errors.
