KAN-35 Adding missing toolboxes

[Kkuntal990]

Below are the test failures due to missing toolboxes

T-test functions:

statcondTest/pairedTTest - requires ttest()

statcondTest/unpairedTTest - requires ttest2()

ANOVA functions:

statcondTest/paired1Anova - requires fcdf() via rm_anova2()

statcondTest/paired2Anova - requires fcdf() via rm_anova2()

statcondTest/unpaired1Anova - requires anova1()

statcondTest/unpaired2Anova - requires anova2()

Error examples:

text
Undefined function 'ttest' for input arguments of type 'double'.
Undefined function 'anova1' for input arguments of type 'cell'.
Undefined function 'fcdf' for input arguments of type 'double'.

Category 2: Numerical Tolerance Failures (3 failures)

These tests fail due to small numerical differences exceeding the 1% relative tolerance:

statcondTest/pairedDimTTest: Multiple p-values differ (0.02 vs 0.03, 0.02 vs 0.01)

statcondTest/unpairedDimTTest: P-value 0.02 vs expected 0.05 (60% error)

statcondTest/unpairedDim2Anova: P-values with 34.9% and 1.7% relative errors
