Hello I am Very new to programming please help me out

I got this error while running

Brace indexing is not supported for variables of this type.

Error in Untitled3 (line 7)
myfile1 = myfile1{1};

[Geoff Hayes]

Raviteja - the error message is telling you that cannot use braces on the myfile1 variable as you are doing at

myfile1 = myfile1{1};

Since you are using imread, then myfile1 is an Image data, returned as an array. What are you trying to accomplish by accessing this variable in this way? Is there a particular dimension of the image array that you want? Please clarify.

[GSN Spidey]

So how do we access this then?

The imread function returns a numeric array, not a cell. See the documentation section on A (link) in the Output Arguments section.
