EXP function 释义 [计]指数函数 行业词典 计算机 指数函数
在MATLAB中，exp函数代表指数函数（exponential function）。它实现了自然指数函数中以e为底的指数计算方法，通过将e的x次方作为结果返回，其中x是参数。例如，exp(1)等于e，exp(-2)等于1/e^2。在MATLAB中，exp函数适用于实数和复数。它是一个广泛使用的函数，有许多应用，例如数学、物理学、工程学和...
Exp(number) The requirednumberargument is a Double or any valid numeric expression. Remarks If the value ofnumberexceeds 709.782712893, an error occurs. The constanteis approximately 2.718282. Note:TheExpfunction complements the action of theLogfunction and is sometimes referred to as the antilogarith...
The EXP function syntax has the following arguments: NumberRequired. The exponent applied to the base e. Remarks To calculate powers of other bases, use the exponentiation operator (^). EXP is the inverse of LN, the natural logarithm of number. ...
