Error Message and Paths

When you get an error message that reads like this:

 Error: File: FinProject_ImgAlign.m
 Line: 3
 Column: 18
 The expression to the left of the equals sign is not a valid target for an assignment.

the code showing the paths:

 LabelDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/'
 imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/FaceImages/'
 DestDir = imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/AlignedFaceImages/'

Please what do you do? I am running MATLAB on a Mac system.

Then type:

edit FinProject_ImgAlign

Copy the whole line 3 and paste it here. Also tell us what version of Matlab are you using.

[Suzzie]

line 3: DestDir = imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/AlignedFaceImages/'

matlab version: 7.10 (r2010a)

Suzzie, why are you assigning a different value to imgDir on two consecutive lines?

Answer 1

[Vieniava]

I think your code suppose to look like this:

LabelDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/'
imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/FaceImages/'
DestDir ='/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/AlignedFaceImages/'

The cause of an error was the third line. You are not allowed to make (double) assigment like:

DestDir = imgDir = 'string'

[Oleg Komarov]

Now I get the problem:

1) I agree with Vieniava

2) If the whole code is defined on a single line, then separate each assignments with ;

Ex:

LabelDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/'; imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/FaceImages/'
