If the comp processor is AMD then you have to select that option
during Matlab installation. I had faced the same problem becuase of
AMD processor.

To rectify the problem, Follow the steps below:

1 - Open %MATLAB7%\bin\win32 in Windows Explorer or through My
Computer. '%MATLAB7%' here is the path where you installed MATLAB.

2 - Find the file named 'blas.spec'. Open this file in Wordpad. You
will see a listing like this:
GenuineIntel Family  5 Model  * atlas_PPro.dll   # Pentium
GenuineIntel Family  6 Model  1 atlas_PPro.dll   # Pentium Pro
GenuineIntel Family  6 Model  3 atlas_PII.dll    # Pentium II
(Klamath)
GenuineIntel Family  6 Model  5 atlas_PII.dll    # Pentium II
(Deschutes)
GenuineIntel Family  6 Model  6 atlas_PII.dll    # Celeron
GenuineIntel Family  6 Model  7 atlas_PIII.dll   # Pentium III
(Katmai)
GenuineIntel Family  6 Model  8 atlas_PIII.dll   # Pentium III
(Coppermine)
GenuineIntel Family  6 Model  9 atlas_PIII.dll   # Pentium M
GenuineIntel Family  6 Model 10 atlas_PIII.dll   # Pentium III
(Cascades)
GenuineIntel Family  6 Model 11 atlas_PIII.dll   # Pentium III
(Mobile)
GenuineIntel Family  6 Model  * atlas_PIII.dll   # Pentium III
GenuineIntel Family 15 Model  * atlas_P4.dll     # Pentium 4
AuthenticAMD Family  5 Model  * atlas_PII.dll    # AMD-K6
AuthenticAMD Family  6 Model  * atlas_Athlon.dll # Athlon/Duron
AuthenticAMD Family 15 Model  4 atlas_Athlon.dll # Athlon 64
AuthenticAMD Family 15 Model  5 atlas_Athlon.dll # Opteron

if you have AMD processor then remove the '*' and put the number '12'.
If your processor is not listed then you can add the line and write
the processor name.
eg.       AuthenticAMD Family 15 Model 12 atlas_Athlon.dll # AMD64


save the file and start the Matlab.
