Calculate the common logarithm of 1. log10 (1) ans = 0. The result is 0, so this is the x-intercept of the log10 function. Calculate the common logarithm of 10. log10 (10) ans = 1.

Get a Trial of MATLAB and Simulink Products If X is a vector, then nansum(X) is the sum of all the non-NaN elements of X.. If X is a matrix, then nansum(X) is a row vector of column sums, computed after removing NaN values..

Y = log10(X) devuelve el logaritmo común de cada elemento de la matriz X. La función acepta entradas tanto reales como complejas. Para valores reales de X en el intervalo (0, Inf), log10 devuelve valores reales en el intervalo (-Inf,Inf). Para los valores reales complejos y negativos de X, la función log10 devuelve valores complejos.

if im calculating a matrix called M, using actual numbers lets call them A,B and reading from another matrix say M2; The java.lang.Math.log10(double a) returns the base 10 logarithm of a double value. Special cases: If the argument is NaN or less than zero, then the result is NaN. If the argument is positive infinity, then the result is positive infinity. If the argument is positive zero or negative zero, then the result is negative infinity. faster "log10" command.

If X is a vector, then nansum(X) is the sum of all the non-NaN elements of X.. If X is a matrix, then nansum(X) is a row vector of column sums, computed after removing NaN values.. If X is a multidimensional array, then nansum operates along the first nonsingleton dimension of X.The size of this dimension becomes 1 while the sizes of all other dimensions remain the same.

log10(eps) is-15.6536 See Also. exp, log, log2, logm TF = isnan(A) returns a logical array containing 1 (true) where the elements of A are NaN, and 0 (false) where they are not.If A contains complex numbers, isnan(A) contains 1 for elements with either real or imaginary part is NaN, and 0 for elements where both real and imaginary parts are not NaN. You should make a test on hMphi each time it is computed and arrange to stop if a NaN is detected so you can check all the values that go into your equation at that point. 0 Comments Show Hide -1 older comments A Problem with log10.

This is the second of the indeterminant forms listed in this section of the Wikipedia page for NaN. $\begingroup$ Of course I understand that Matlab does not simplify $\log(\exp(-x))$ for me.

For complex-valued input, log10 is a complex analytical function that has a branch cut [-inf, 0] and is continuous from above on it. log10 handles the floating-point negative zero as an infinitesimal negative number, conforming to the C99 standard. References. 1
