# MATC Operators

a,b and c ordinary matrices

l,t and r logical matrices

s,n and m scalars

b=a' is transpose of matrix a.

b=@a evaluate content of a string variable a as a MATC statement.

elementwise logical not of if x is not zero.

if a is a square matrix and s is integral, a matrix power is computed, otherwise an elementwise power.

c=a*b if a and b are compatible for matrix product, that is computed, otherwise if they are of the same size or at least one of them is scalar, an elementwise product is computed.

elementwise multiplication of a and b.

c=a/b is fraction of a and b computed elementwise.

c=a+b is sum of matrices a and b computed elementwise.

c=a-b is difference of matrices a and b computed elementwise.

l=a==b equality of matrices a and b elementwise.

l=a<>b inequality of matrices a and b elementwise.

l=a<b true if a is less than b computed elementwise.

l=a>b true if a is greater than b computed elementwise.

l=a<=b true if a is less than or equal to b computed elementwise.

l=a>=b true if a is greater than or equal to b computed elementwise.

a=n:m return a vector of values starting from n and ending to m by increment of (plus-minus) one.

elementwise logical and of a and b.

l=a|b elementwise logical or of a and b.

c=a?b reduction: set values of a where b is zero to zero.

resize a to matrix of size n by m.

b=a assing a to b.
