How save the image using strcat ?

Hi, I want save my Image in folder there is include the name of image using strcat, I try but error ?

here my function :

function out = uji(fname)
    
    im=imread(fname);
    
    outdir = 'Image Result';
    mkdir(outdir);
    imwrite (strcat(fname(im(outdir, '1_ori.bmp'))));
    
out = im;

Could help me please ? thank you

This does not make much sense:

im(outdir, '1_ori.bmp')

If im is an image array, why are you trying to index into it using two chracter vectors?

fname(im(outdir, '1_ori.bmp'))

If fname is a character vector or a string, why are you trying to indexing into it using an image array?

strcat(fname(im(outdir, '1_ori.bmp')))

What are you concatenating together? (There is only one input argument, so you concatenate one thing ... with nothing else).

I create this code, but the result not save in folder

outdir = 'Image Result';
mkdir(outdir);
imwrite(im,strcat(outdir, fname, '1_ori.bmp'));

How I can save inside folder ? Thanks

Do not use strcat to build paths. Always use fullfile that is guaranteed to use the correct path separator regardless of which OS you use.

Yes sir. Thank you for all the answer. I get what I want.
