Hi everybody!
I have the following problem: I want to use the function 'imregcorr' from the Image Processing Toolbox. The toolbox seems to installed correctly:
------------------------------------------------------------------------------------------------ MATLAB Version: 8.1.0.604 (R2013a) MATLAB License Number: STUDENT Operating System: Microsoft Windows 7 Version 6.1 (Build 7601: Service Pack 1) Java Version: Java 1.6.0_17-b04 with Sun Microsystems Inc. Java HotSpot™ Client VM mixed mode ------------------------------------------------------------------------------------------------ MATLAB Version 8.1 (R2013a) Simulink Version 8.1 (R2013a) Computer Vision System Toolbox Version 5.2 (R2013a) Control System Toolbox Version 9.5 (R2013a) DSP System Toolbox Version 8.4 (R2013a) Data Acquisition Toolbox Version 3.3 (R2013a) Image Acquisition Toolbox Version 4.5 (R2013a) Image Processing Toolbox Version 8.2 (R2013a) Instrument Control Toolbox Version 3.3 (R2013a) Optimization Toolbox Version 6.3 (R2013a) Signal Processing Toolbox Version 6.19 (R2013a) Simulink Control Design Version 3.7 (R2013a) Statistics Toolbox Version 8.2 (R2013a) Symbolic Math Toolbox Version 5.10 (R2013a)
But when I want to use the function I get the following error: Undefined function or variable 'imregcorr'.
Anyone an idea?

The function imregcorr was introduced in the R2014a release. Looks like you have an R2013a version of IPT, that's why you don't have it.

According to the note at the end of the rgb2lab documentation page, that function was introduced in release R2014b so you will not be able to use it in release R2013a of the toolbox.
