REPOP -- efficient replicating n-d array operations 1.0

Replicating arithmetical and logical operators.Does element by element operations on X and Y where non-same sized dimensions are implicity wrapped round to match the size of the largerto give a result matrix Z with size max(size(X),size(Y));In general this is at least 2x faster than the equivalent matlab code using repmats and has the advantage of requiring no additional memory. Example Usage: X = randn(10000,10); example signal with data in rows stdX = repop(X,mean(X,1),'-'); subtract the mean vector stdX = repop(stdX,std(stdX,0,1),'/'); % divide by std-deviationOperator can be one of:Arthemetical -- returns a double matrix '+','.+',plus - Implicitly repmatted elementwise addition '-','.-',minus - Implicitly repmatted elementwise addition '*','.*',times - Implicitly repmatted elementwise multiplication '^','.^',power - Implicitly repmatted elementwise raise X to power Y '','.',ldivide- Implicitly repmatted elementwise divide Y by X '/','./',rdivide- Implicitly repmatted elementwise divide X by YRelational -- returns a logical matrixN.B. for complex inputs the ,= operators are based upon abs(x) (not real(x) as in matlab) '==',eq - Implicitly repmatted elementwise equality '~=',ne - Implicitly repmatted elementwise dis-equality '' ,gt - Implicitly repmatted elementwise greater than '=',ge - Implicitly repmatted elementwise greater than equal
