The sarek function analyzes a sparse matrix for integrity. Patterned after the original spok function by Tim Davis. Requires a C compiler to compile the C source code sarek.c into a mex routine. Should work for both R2017b- and R2018a+ MATLAB versions, but I am only able to test the R2018a+ version currently. Let me know if you find any issues. Self building.
Syntax:
bad = sarek(s)
Where s = A sparse matrix (real or complex, double or logical)
bad = Number of errors found
Checks for the following errors:
M < 0
N < 0
Nzmax < 1
Jc = NULL
Jc[0] ~= 0
Jc[N] > Nzmax
(M==0 || N==0) && Jc[N] ~= 0
Jc[j] < Jc[j-1]
Ir == NULL && Jc[N] > 0
Jc[j] > Nzmax
Ir[i] < 0 || Ir[i] >= M
Ir[i] <= Ir[i-1]
Pr == NULL && Jc[N] > 0
Pi == NULL && Jc[N] > 0
Pr[i] = 0 for real or logical matrices
Pr[i] = 0 && Pi[i] == 0 for complex matrices
